(Date of Event Which Requires Filing of this Statement)

This statement relates to shares of Common Stock (the "Stock") of Mace Security International, Inc. (the "Issuer"). The principal executive office of the Issuer is located at 1000 Crawford Place, Suite 400, Mt. Laurel, NJ 08054.

The persons filing this statement and the persons enumerated in Instruction C of Schedule 13D and, where applicable, their respective places of organization, general partners, directors, executive officers and controlling persons, and the information regarding them, are as follows:

The source and amount of funds used in purchasing the Stock were as follows:

As disclosed in its prior filings of Schedule 13D, the Filers ("Lawndale") have sent a number of letters (the "Prior Letters") to the Board of Mace Security International ("Mace" or the "Company"), which were attached as Exhibit B to Schedules 13D, Amendments No. 1 through No. 5, detailing Lawndale's concerns regarding several corporate governance issues including, but not limited to, what Lawndale believes to be insufficient independent composition and structuring of Mace's Board of Directors. As further detailed in the Prior Letters, Lawndale believes that the problems with Mace's Board of Directors have contributed to the Company's poor performance and decline in its stock price.

On September 18, 2007, Lawndale sent Mace a letter (a copy of which is attached as Exhibit B hereto, and incorporated by reference in this filing) in which Lawndale submitted notice (the "Lawndale Notice") of Lawndale's intent to nominate Eugene Davis, Gerald LaFlamme, Philip Livingston and Dennis Raefield (the "Independent Nominees") for election to Mace's Board of Directors. The Lawndale Notice also set forth several proposals (the "Shareholder Proposals") for stockholder approval at Mace's 2007 Annual Meeting. As described in the Lawndale Notice (as well as in the Prior Letters), Lawndale's believes that adding new, Independent Directors who have no ties to the current management of the Company and have not been selected by the management of the Company will improve the functioning of the Board. Similarly, Lawndale believes that the Shareholder Proposals, taken both individually and as a whole, will help improve the governance of the Company, and thereby lead to improved performance.

As disclosed in the Lawndale Notice, Lawndale intends to file a proxy statement with the Securities and Exchange Commission for the purpose of soliciting proxies with respect to election of the Independent Nominees and approval of the Shareholder Proposals. Lawndale believes, given the operating history and oversight experience of the Independent Nominees, they would individually, and together, add significant expertise and value to Mace's Board. Further, Lawndale believes that the Shareholder Proposals would greatly improve Mace's governance mechanisms.

As detailed in the Prior Letters and the Lawndale Notice, Lawndale believes a substantial change in Mace's Board is necessary to improve the quality and functioning of the Company's independent directors, and ultimately the Company's performance. Lawndale's only goal is to improve the Company's governance structure so as to enhance shareholder value. Through its Prior Letters and communications setting forth several proposals submitted over the past year, Lawndale has attempted to achieve this goal on a cooperative basis with minimum expense and distraction. Lawndale has had discussions with Mace's management and Board in an effort to resolve this matter in a constructive way and to avoid a proxy contest. Unfortunately, such discussions to date have been fruitless and, in Lawndale's opinion, only highlight the existing Board's lack of independence. As a result, Lawndale currently believes that the only way Lawndale can achieve the improvements in the Company's governance structure necessary to create value for all shareholders is to conduct a proxy contest to change the Board and approve the other items set forth in the Lawndale Notice. As described in the Prior Letters and the Lawndale Notice, Lawndale believes that replacing all of the Board members (other than Mr. Paolino) with truly qualified and independent directors who will act solely in the best interests of the Company's shareholders is the best way to improve the Company's governance structure.

Lawndale has been and may continue to be in contact with Mace management, members of Mace's Board of Directors, other significant shareholders and others regarding these and additional steps that Mace could employ to maximize shareholder value.

Lawndale believes the public market value of Mace, currently trading below it's tangible book value, is undervalued by not adequately reflecting the value of Mace's assets and business divisions. Lawndale acquired the Stock solely for investment purposes, and Lawndale may from time to time buy or sell the Stock at its discretion.

Lawndale incorporates by reference its activities and discussions disclosed in its prior Schedules 13D to the extent not inconsistent with the discussion herein.

Dear Mr. Kramer:

This letter is written on behalf of our clients, Lawndale Capital Management, LLC, Diamond A Partners, L.P. and Diamond A Investors, L.P. (collectively "Lawndale"), beneficial holders of 1,574,479 shares of common stock, par value $0.01 per share (the "Shares"), of Mace Security International, Inc., a Delaware corporation (the "Company").

As holders of record of the Shares, on behalf of Lawndale, we hereby provide notice to the Company that Lawndale intends to nominate Eugene I. Davis, Gerald T. LaFlamme, Philip B. Livingston and Dennis R. Raefield (sometimes referred to herein as the "Nominees") for election to the Company's Board of Directors (the "Company Board") at the 2007 Annual Meeting of Stockholders of the Company (including any adjournments or postponements of such meeting and any meeting held in lieu thereof, the "Annual Meeting"). Please also be advised that Lawndale intends to solicit proxies with respect to the election of the Nominees. Lawndale also intends to vote for the election of Louis D. Paolino, Jr. to the Board.

It is the understanding of Lawndale that the stockholders of the Company will be asked to elect five (5) directors at the Annual Meeting, each to serve for a one year term ending on the date of the annual meeting of stockholders of the Company to be held in 2008. Lawndale reserves the right to nominate a substitute person for election as a director in the event that any Nominee is unable or unwilling to serve as a director or the Company makes or announces any change to the Bylaws of the Company (the "Bylaws") or takes or announces any other actions that are designed to, or have the effect of, disqualifying any of the Nominees.

Lawndale reserves the right (i) subject to any limitation resulting from an equitable and proper application of the Bylaws, to nominate additional nominees to fill a director's position, (ii) to nominate additional nominees to fill any director positions created by the Company's Board prior to or at the Annual Meeting, or (iii) to designate any such nominees as nominees with respect to any class or classes of directors to be elected at the Annual Meeting.

Lawndale also hereby provides notice to the Company that Lawndale also intends to propose for stockholder approval at the Annual Meeting resolutions effecting the proposals listed on Annex A to this letter (collectively, the "Proposals").

Lawndale's interest in the election of the Nominees and the approval by stockholders of the Proposals is derived from Lawndale's ownership of the Shares, as noted above.

This letter also constitutes notice under Rule 14a-4(c)(2)(i) that Lawndale intends to deliver a proxy statement and form of proxy to holders of at least the percentage of the Company's voting shares required under applicable law to approve the slate of nominees set forth above and the Proposals.

Lawndale reserves the right, in the event such information shall be or become inaccurate, to provide corrective information to the Company as soon as reasonably practicable, although Lawndale shall not be obligated to update any information that may change from and after the date hereof. Lawndale reserves the right to give further notice of its intention to present additional business or further notice of additional nominations, in each case, to be conducted or made at the Annual Meeting or other meeting of the Company's stockholders or to revise the nominations described herein.

The giving of this notice is not an admission that this notice is required by any provision in the Bylaws, the General Corporation Law of the State of Delaware or any other applicable governing document or provision of law. Lawndale reserves all rights to assert a claim for any damages or costs that it may sustain or incur, including attorneys' fees, in the event of any dispute concerning the validity of this notice.
