These feel a good thickness to me, not too thin and not too thick. Very easily trimmed with scissors to fit my needs. I bought these to slip over plastic pegs on our Container Store hamper frame, since the hamper has plastic grommets in the corners that slip over plastic pegs, they just kept slipping off with the slightest bump. After trimming these caps to size, these 5/16" vinyl caps were the perfect fit and stopped the darn hamper from slipping off it's frame! SO HAPPY! My only thing is that these did not come in white, which my hamper and frame is. So these black caps stick out like a sore thumb (aka noticeable), but I DON'T CARE BECAUSE I'M SO HAPPY the hamper is finally staying in place! At least these weren't bright colored, where my kid might see it as something to play with.

I bought these to replace the age-hardened Seastar bleeder replacement covers on my outboard. Perfect diameter and just a bit too long. Can always trim to length, but I see no reason to.
