Cash transmittal bags are made of strong, clear, 2.75 mil polyethylene and can be used to hold valuables. The tamper-resistant adhesive seal at the top is permanent. Strong, heat-sealed seams hold up to rough treatment. Write on the large, imprinted white-shaded box to identify contents. Preprinted box labels include register number, date, cashier, cashier's name, currency, coin, checks, credit card, misc, total and comments. A line with "register closed by" prompts a signature.
