The Red TamperColor® Tamper Evident Security Label Seal Sticker is a ready-to-deploy stock tamper seal requiring no custom print setup or lead time. Apply directly to your product, packaging, or asset for immediate tamper-evident protection. Available in a 500-label small operational supply, this Red compact rectangle (1" x 0.5" / 25mm x 13mm) format is suited for low-volume ongoing operations and boutique security programs.

The high-visibility red face serves as an immediate, universally understood alert color — making red TamperColor® labels the natural choice for security-critical applications where a compromised seal must be unmistakably obvious. Red signals danger, stop, and alert across virtually every industry and culture, amplifying the deterrent effect of the tamper-void mechanism. The 1" x 0.5" (25mm x 13mm) compact rectangle is one of the most versatile TamperColor® sizes — wide enough for clear visibility and meaningful tamper evidence, yet compact enough for the majority of standard packaging closures, product boxes, and device interfaces.

When any removal attempt is made, the TamperColor® label responds with an irreversible color-change void pattern — the proprietary adhesive system leaves a permanent, chromatic tamper-evident mark on both the label face and the substrate surface that cannot be cleaned off, reapplied, or disguised. Unlike standard tamper-evident labels that simply fragment or leave residue, TamperColor® creates a vivid color-pattern void that is immediately and unmistakably visible — even to untrained eyes at a glance.

The blank face can be hand-marked post-application or used as a clean, unprinted tamper indicator. For organizations needing printed content such as barcodes, serial numbers, or logos, see the Custom Print (CTC) or pre-printed Warranty Void (GTC) versions.
