The White 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 White compact rectangle (1" x 0.5" / 25mm x 13mm) format is suited for low-volume ongoing operations and boutique security programs.

The clean white face provides maximum print contrast for text, barcodes, QR codes, and logos — making white TamperColor® labels the most versatile and widely used option in the TamperColor® line. White suits virtually any application requiring high-readability security seals that also carry printed identification content alongside the tamper-evident 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.
