The pocket puller is an accessory for helping divers with gloves or mitts to open and close pockets / zips more easily. Consists of a yellow 22mm nylon ball with 4mm black nylon cord approx 100mm in length. You are buying three pocket pullers. I am happy to increase or decrease the length to suit your requirements at no extra cost. Orkney Sporting Goods manufactures quality products for the scuba industry.
