Item 7    Financial Statements and Exhibits.


          (c) The following Exhibits are hereby filed as part of this Current
          Report on Form 8-K.

          99.1   Press Release issued by Mace Security International, Inc. dated
          March 12, 2004.

Item 12   Results of Operations and Financial Condition

          On March 12, 2004, Mace Security International, Inc. issued a press
          release announcing its financial results for the fiscal quarter and
          year ended December 31, 2003. A copy of the press release is attached
          as Exhibit 99.1 and is incorporated herein
          by reference in its entirety.

          The press release contains a non-GAAP financial measure, EBITDA.
          EBITDA is calculated as income before cumulative effect of a change in
          accounting principle adding back interest expense, income taxes,
          depreciation and amortization expense and certain non-cash charges. We
          believe that EBITDA, as presented, represents a useful measure of
          assessing the performance of our operating activities and resources
          available for strategic opportunities, as it reflects our earnings
          trends, without the impact of certain non-cash and unusual charges or
          income. EBITDA is also used by our creditors in assessing debt
          covenant compliance. We understand that, although security analysts
          frequently use EBITDA in the evaluation of companies, it is not
          necessarily comparable to other similarly titled captions of other
          companies due to potential inconsistencies in the method of
          calculation. EBITDA is not intended as an alternative to cash flow
          provided by operating activities as a measure of liquidity, as an
          alternative to net income as an indicator of our operating
          performance, nor as an alternative to any other measure of performance
          in conformity with generally accepted accounting principles.


                                   SIGNATURES

Pursuant to the requirements of the Securities and Exchange Act of 1934, the
registrant has duly caused this report to be signed on its behalf by the
undersigned hereunto duly authorized.
