10,000 Tamper Evident Holographic Bright Black Security Label Seal Sticker TamperMax, Rectangle 1" x 0.375" (25mm x 9mm). Printed: Warranty Void if Removed.

What sets this bright black label apart is the holographic substrate itself: a microstructured film that bends light into shifting colors no flatbed printer can replicate.

The polyester construction is flexible enough to bend around a 90-degree edge without cracking, which matters on enclosures and panel seams where the label has to wrap a corner rather than lie flat.

The rectangular shape spans seams and box flaps effectively, giving solid coverage across a wider gap than a small round label could. Popular for cold-chain products, pharmaceutical packaging, and electronics where both durability and tamper evidence are non-negotiable.

This pack contains 10,000 labels. This label ships pre-printed with the warranty void message already applied, so it's ready to use straight out of the box.
