BUSHIBU USB Cover Cap, 20 Pcs Black Clear Plastic USB A Male Anti-Dust Plug Cover for Personal Computer

better than expected. they fit snugly but not too snugly

I ordered some of these because I put USB sticks in my pocket, where lint and sometimes even dirt tend to collect. I garden so I'm in the dirt at times. I've used these on a few different brands of sticks, USB cables and other USB plugs. They fit snug enough to stay on until pulled off but are lose enough you don't have to use a screwdriver or pair of pliers to get it off. I'd say it is just about right. I've yet to have one come off without me taking it off. The material it is made of is a bit sticky like so it helps keep it in place. These are really nice and does the job really well.

These work well if you've lost the cap to a flash drive, or have a lot of little small sized dongles like unifying receivers from logitech or bluetooth adapters or whatever. It is hard plastic, no flex to it at all, and they fit very, very snugly - almost too tight on a few drives, which makes it hard to remove some of them. It didn't fit one of my drives at all, but that's a special one off drive made by Asus for my motherboard, so that might be why.

Nice USB Covers and the price was right. They work well to replace the original USB covers.

Fit is great, nice and snug

These fit securely, and are easy to put on and remove. Good price, too.

Fits well and helps protect the USB opening from damage

Excellent, just what I needed! Plenty of covers now! Yey

Tapones que protegen tus dispositivos USB, memorias, cables, adaptadores, quedan perfectamente en los dispositivos y los protegen del polvo que dondequiera con el tiempo se acumula, los recomiendo

Pensé que por el precio serían frágiles o no servirían, pero si funcionan muy bien
