This tamper-evident version of Univenture’s adhesive sleeve has a tear-out front strip that reveals if the sleeve has been opened since it was attached. Insert the disc from the back, peel off the waxed backing, and apply it to a folder, binder, book, magazine, or any smooth surface for a secure way to distribute optical discs. Ideal for sensitive applications where tamper security is needed. Measures 5 1/4″ (W) x 5″ (H).
