Rope key ring loops. Assorted colours.....Not one is the same!
Simple things, but you end up using them every day.
Made from strong rope that can handle being pulled, dropped, stuffed in a bag, clipped onto anything. Finished with a solid metal ring so your keys stay where they should.
Easy to grab, easy to find, especially when they disappear to the bottom of a bag or a car door pocket.
Clip it onto your belt, your bag, or just keep it in hand. One of those small pieces that quietly does its job, and does it well.
