The pocket puller is an accessory for helping divers with gloves or mitts to open and close pockets / zips more easily. Consists of a 22mm nylon ball with 6mm black bungee approx 100mm in length. You are buying three heavy duty pocket pullers. I am happy to increase or decrease the length to suit your requirements at no extra cost.
