Grabbit® has a pleasing contemporary design with a shallow bowl surface to gather pins and a comfortable round shape to hold in your hand. Includes 50 colorball plastic head Grabbit™ Steel Sewing Pins. The pins have ample sized 4mm plastic heads and are 1-1/2" long. Grabbit® is safe near computer sewing machines since magnetic fields will not affect computer chips and many sewing machines actually have magnets in the inner workings.
