Each has a round tail, a metal clip in the polypropylene head and a flag with a hole for hanging a tag. Choose the length by the loop you need. Feed the tail through the head and pull tight. The catalogue lists 142 N tensile and 6.1 g per piece (values given once for the range). MOQ is 2,000 pieces, packed 200 per bag and 2,000 per carton.
How it locks
The round tail passes one way through the metal clip and cannot be loosened.
