The Brady TL-PK-12 Tamperseals™ are tamper seals that protect your warranty exposure by sealing access points. Brady's Tamperseals are designed for sealing access points, protecting adjustments and sealing enclosures. These labels are made to fracture easily in order to show signs of product tampering and to prevent one-piece label removal. Tamperseals come in a 20-page pocket size book. Brady also offers printable tamper evident labels for use with thermal trasfers printers.
