              Notes to CONDENSED CONSOLIDATED Financial Statements

                                   (UNAUDITED)

Note 1 -- Basis of Presentation

In the opinion of management, the accompanying condensed consolidated financial
statements include all adjustments necessary to present fairly the financial
position, results of operations and cash flows. However, the financial
statements do not include all of the disclosures normally required by accounting
principles generally accepted in the United States of America or those normally
made in the Company's annual report on Form 10-K. Please refer to the Company's
annual report on Form 10-K for the year ended December 31, 2002 for such
disclosures. The condensed consolidated balance sheet as of December 31, 2002
was derived from the audited consolidated balance sheet as of that date. The
results of operations for interim periods are not necessarily indicative of the
results to be expected for the full year.

Note 2 -- Contingencies

The Company has been involved in certain environmental and other matters.
Additionally, the Company has been involved in numerous legal actions relating
to the use of certain latex products, which the Company distributes, but does
not manufacture. The Company is one of many defendants. The Company has been
released from the majority of the lawsuits. While one lawsuit remains, it is
still in the preliminary stages and it has not been determined whether the
Company's products were involved. Based on information available, the Company
believes there will not be a material adverse impact on financial position,
results of operations, or liquidity, from these matters, either individually or
in aggregate.

Note 3 -- Accounting for Stock-Based Compensation

 At March 31, 2003, the Company has one stock-based employee compensation plan.
The Company has elected to adopt the disclosure only provisions of Statement of
Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation,
and continues to measure costs for its employee stock compensation plans by
using the accounting methods prescribed by APB Opinion No. 25, Accounting for
Stock Issued to Employees, which allows that no compensation cost be recognized
unless the exercise price of the options granted is greater than the fair market
value of the Company's stock at date of grant. Accordingly, no stock-based
employee compensation cost is reflected in net income, as all options granted
had an exercise price equal to the market value of the underlying common stock
on the date of grant. The following table illustrates the effect on net income
and earnings per share as if the Company had applied the fair value method under
SFAS No. 123, Accounting for Stock Based Compensation, to stock-based employee
compensation.

Note 4 -- Litigation Settlement

As a result of significant developments in the first quarter of 2003 the
Company's German subsidiary settled litigation for $175,000. This exceeded
previous accruals by $153,000 and has been charged to expense.

Note 5 -- Income taxes

In 2002, the Company recognized a significant one-time income tax benefit
associated with liquidating its UK business. The benefit recognized was
substantially in excess of income taxes computed at the statutory rate. In
2003, consolidated income before income taxes includes losses of foreign
subsidiaries with no income tax benefit resulting in a high effective income tax
rate.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

                    For the Three Months Ended March 31, 2003

Results of Operations

Net Sales

Traditionally, the Company's sales are stronger in the second and third
quarters, and weaker in the first and fourth quarters of the fiscal year due to
the seasonal nature of the business specific to the back-to-school season.
Consolidated net sales for the quarter ended March 31, 2003 were $7,189,000
compared with $6,755,000 for 2002, a 6% increase. Excluding the favorable effect
of currency gains in Canada and Europe the net sales increase represented 4%.
The sales increase was mainly driven by a 13% increase in the U.S. due to the
success of new product launches. International sales were down 18% in local
currency principally due to discontinuing certain product lines in the UK
business and a weak economy in Germany.

Gross Profit

The gross profit for the first quarter of 2003 was $2,882,000 (40% of net sales)
compared to $2,143,000 (32% of net sales) for the first quarter of 2002. The
introduction of new products coupled with higher sales to a significant customer
in the U.S., positive impacts from product rationalization efforts in Europe and
overall productivity gains were the main reasons for the improved gross margins.
The U.S. accounted for approximately 60% of the 8% point improvement. Gross
margin is expected to vary in future quarters depending on product, customer and
entity mix.

Selling, General and Administrative Expenses

Selling, general and administrative ("SG&A") expenses for the first quarter of
2003 were $2,301,000 (32% of net sales) compared with $1,943,000 (29% of net
sales) for the same period of 2002, an increase of $358,000. Major contributors
to the increase were market research, new product development and the addition
of sales executives in Canada and Europe.

Interest Expense

Interest expense for the first quarter of 2003 was $79,000, compared with
$147,000 for 2002, a $68,000 decrease. This is mainly attributable to the
decline in debt and lower interest rates. Total debt declined to $5,548,000
million at March 31, 2003 compared to $6,871,000 million at March 31, 2002.

Other Expense

Net other expense was $150,000 in the first quarter of 2003 compared to net
other income of $84,000 in the first quarter of 2002. The change from 2002
relates to the settlement of a lawsuit in Germany in late March of 2003 and the
gain on sale of equipment in 2002.

Income Before Income Taxes

Income before income taxes was $352,000 in the first quarter of 2003 compared
with $137,000 in the first quarter of 2002, an increase of $215,000. Pretax
income for North America was $730,000 compared to $312,000 in 2002. The European
operations lost $378,000 including a one-time expense of $175,000 for settlement
of a lawsuit. The pretax loss in Europe for the first quarter of 2002 was
$175,000.

Income Taxes

Income tax expense for the first quarter of 2003 was $274,000 compared to
$15,000 in the first quarter of 2002. In 2002, the Company recognized a
significant one-time income tax benefit associated with liquidating its UK
business. The benefit recognized was substantially in excess of income taxes
computed at the statutory rate. In 2003, consolidated income before taxes
includes losses in foreign subsidiaries with no income tax benefit resulting in
a high effective income tax rate.

Net Income

Net income for the first quarter of 2003 was $78,000, or 2 cents per share
(diluted), compared to a net income of $122,000, or 3 cents per share (diluted)
for the same period of 2002.

  Working capital.....................       $8,900,000            $8,516,000
  Current ratio.......................        2.44 to 1             2.33 to 1
  Long-term debt to equity ratio......            23.0%                 24.0%

During the first three months of 2003, total debt increased by $332,000 compared
to total debt at December 31, 2002 principally as a result of net additional
short-term borrowings to fund inventory purchases in anticipation of next
quarter's seasonal sales volume.

The Company has a revolving loan agreement, which allows for borrowings up to a
maximum of $10,000,000 based on a formula, which applies specific percentages to
balances of accounts receivable and inventory. Interest is payable monthly and
is charged at the LIBOR rate plus 1.75 percent. As of March 31, 2003, $4,481,612
was outstanding and $2,429,460 was available for borrowing under this agreement.
Maturities of long-term debt follow: 2004 - $2,913,000, 2005 - $1,120,000, and
2006 - $448,612. All outstanding borrowings are due on July 31, 2005.

Cash expected to be generated from operating activities, together with funds
available under its existing loan agreement, are expected, under current
conditions, to be sufficient to finance the Company's planned operations over
the next twelve months. Over that same period, the Company does not expect to
make significant investments in plant, property, and equipment.
