AFUNTA Foam Floating Keychain, 10 Pcs Oval Foam Float Key Chain for Outdoor Sports, Fishing, Boating – Orange/Yellow/Black/Blue/Red, Red, S

Add it to your glasses in water or keys

Always find uses on the boat. Not just keys

I use these for keys to guest accommodations. The bright ones are best, and easier to see if dropped on the ground. It's also great that they float, as guests use the boats and may drop them in the water.

I use for iron ons to promote me

Good value
