This UNIQUE braided elastic bundle is a bulk option for sewing projects that use narrow braided elastic inside a casing for a clean finish. The set includes 5 packs of white braided elastic, and each pack is listed as 3 mm wide by 72 m long for high volume sewing and production work. Store the packs clean and dry and test stretch and recovery on scrap fabric, so you can confirm performance before cutting and stitching.
