WaferSeals.com Product Changes

Since we believe clear poly tabs without perforations may tear a mailing piece when opened, we recommend that our mailing customers use the TransUltra ™ product which is a lot clearer than regular translucent material and will tear easily even without a perforation. TransUltra ™ paper tabs. The TransUltra ™ product has become very popular resulting in a much lower price, which has lead us to eliminate our regular translucent product entirely.

We have done everything possible to ensure a smooth transition for ourselves and our more than 2000 customers. Please understand that discontinued products cannot be reproduced.
