Here's an easy solution for keeping your USB A devices free from dust and other unsavory particulates. These squishy Silicone USB A Dust Cover Inserts slip neatly into any computer or device with a standard USB A socket.

Comes in a pack of ten, so you're set even if you have a computer or hub with a lot of ports, or if you lose some.

We also have these covers for USB C and for RJ-45/Ethernet ports.
