500 Black TamperGuard Tamper Evident Security Label Seal Sticker Non Residue, Round/ Circle 0.75" diameter (19mm). Printed: Warranty Void if Removed + Serial Number.

TamperGuard's non-residue adhesive is what makes this black label practical on painted panels and glass — no film, no cleanup, just a clear tamper signal if disturbed.

It's built to perform reliably both indoors and outdoors, holding adhesion and tamper function across a wide temperature range without becoming brittle in the cold or losing tack in the heat.

The round shape is a natural fit for jar lids, tube caps, and other circular openings. Popular for cold-chain products, pharmaceutical packaging, and electronics where both durability and tamper evidence are non-negotiable.

This pack contains 500 labels. This label ships pre-printed with a warranty void message and sequential serial number already applied — ready to use with no setup required.
