Cordlocks are used in conjunction with elastic cord. They enable you to pull the elastic cord (plain non-stretchy ties would work as well!) as tightly as you desire and then to lock the elastic at the desired tension. A great product for outerwear, pants, and bags.
This size of cordlock works with 3mm cord.
