40cm H Seal – Heavy Duty Pull Tight Security Seal Standard Numbered Yellow 1000pcs

The 40cm H Seal is a robust, tamper-evident pull-tight security seal designed for applications where both strength and security are essential. Manufactured from high-quality polypropylene with a stainless steel locking insert, the seal provides clear visual evidence of tampering if cut or forcibly opened.
