Set of 12 11" zippers Pants zippers with gold-colored metal teeth, Size 3.5 Durable and handsome Bias Bespoke brand - a small "BIAS" is engraved into the puller Imported exclusively by Bias Bespoke Supply Co. Good quality size 3.5 pants zippers with gold-colored metal teeth and beautiful tape colors. These zippers are very strong and are our Bias Bespoke brand (a small "BIAS" is engraved into the puller). The puller slides easily along the teeth, and locks in place when it is flush against the teeth so that the zipper can't gradually open on it's own, but only when you want it to.
