WELSTIK Tamper Tape Red Tamper Evident Security Seals Tape, Transfer Tamper Proof Security Void Tapes (Red, 1.88 inch x 55 Yards)

There's a learning curb on how to properly handle this tape. Don't use it in a warm or hot environment. The adhesive will stick to your fingers — a lot! — so there will be a significant amount of wasted tape until you perfect your handling technique. Other than that, this product worked perfectly as shown and described. (I know that because Customs tried to pull off the tape and put it back on)

A bit confused how it works at first.... realised later when I rub some of its sticky, text then shows.

Excelente producto. Se pega bien a todo menos si encimas la cinta en sí misma, todo lo marca si lo despegas.

جميل جدًا وأنصح بشراءه

Excelente producto. Se pega a todo salgo que se encime la cinta, todo al despegarse se marca con letras si lo despegas.
