Use these flexible plastic end caps to cleanly finish the cut ends of Rigilene polyester boning. Rigilene's ends can feel pokey, but these caps eliminate any pokey feeling. They have a hole in the end which you can sew through to the Rigilene itself to keep the caps in place. 24 Pieces of 1/4" or 1/2" wide (7mm or 12mm), Black or White.
