The Rainbow 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 250-label starter/evaluation pack, this Rainbow compact rectangle (1" x 0.5" / 25mm x 13mm) format is suited for testing, pilot programs, or targeted specialty applications.

The dazzling rainbow holographic finish produces a dynamic, iridescent color-shift effect that changes appearance at different viewing angles — serving simultaneously as a premium visual authentication feature and a tamper-evident seal. Rainbow TamperColor® labels are virtually impossible to replicate with standard printing, making them a natural choice for high-value goods and branded authentication programs. 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.
