Hamilton Poppies Adjustable Break-A-Way Cat Collar is made of a durable high quality nylon that is designed not to fray. Patented breakaway clip releases when it becomes entangled in bushes, fences, trees, etc., enabling your cat to slip out to freedom. Includes a matching color bell. Adjustable from 8" to 12".
"This snag proof adjustable safety cat collar with bell has an elastic safety band that stretches when it is caught," was part of the product description. The collar I received, while of fine quality, did not have any kind of elasticity.
