(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:

On August 9, 2007, Lawndale sent Mace's Corporate Secretary a letter (the "Demand Letter") (a copy of which is attached as Exhibit B hereto, and incorporated by reference in this filing) pursuant to Section 220 of the General Corporation Law of the State of Delaware and the common law of the State of Delaware, for Lawndale and its agents to inspect, no later than August 23, 2007, certain documents and records of Mace, including, but not limited to, its stockholder lists.

As disclosed in the Demand Letter, its purpose is to enable Lawndale and its agents to communicate with Mace's shareholders with respect to matters relating to their mutual interests as shareholders. As disclosed in Lawndale's Prior Letters, such matters could include, but are not limited to, nominating various individuals to Mace's Board of Directors as alternatives to current Board members and/or to take other such action as Lawndale believes, in its sole judgment, may be necessary and/or appropriate to address Mace's governance weaknesses for the purpose of enhancing Mace's long-term sustainable value.

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 Mace'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.

The beneficial ownership of the Stock by each Filer at the date hereof is reflected on that Filer's cover page.

The Filers effected the following transactions in the Stock in open market transactions on the dates indicated, and such transactions are the only transactions in the Stock by the Filers since June 18, 2007:
