Most USB sticks no longer have cases. Since I carry around a ring of USB sticks, I prefer to keep the ends closed. For dust but mainly to protect the end while I toss it in my work bag. They fit snugly on all my USB sticks and don't fall off. Only time will tell on durability but they look good and have held up well so far. This is for: SJZBIN dust covers for USB plugs
