Metal detectable silicone lanyards are produced from 1.0mm thick food-grade silicone sheeting, containing evenly dispersed metal detectable additives. This silicone lanyard features a 6mm diameter hole at the back of the neck to act as a deliberate weak point allowing the lanyard to break at a reasonable force to prevent trapping accidents. Feature loop and crab claw connectors. Sold as 1 each.
