3/8" Rubber Swimwear Elastic
Filpar Rubber Elastic features a silicone coating on the ribbed surface that grips the fabric as you are sewing and serging. This ribbed surface prevents the “elastic creep” that sewers find so frustrating. The Swimwear Elastic is available in a width of 5/16″ (9 mm), so it is a bit narrower than the standard 3/8″ swim elastics. It is .9 mm thick, giving it a lower profile.
This elastic is chlorine and salt resistant. It is made from 100% rubber, with a silicone coating for ease of use.
