The most flimsy swab ever. My daughter loves this charm! They will begin to stink. I think this allows the adhesive to bond with the wall surface for a tighter grip. Anyway, the important things are that the mouse feels extremely good in the hand, which makes it comfortable to use even if youre on the computer for hours at a time. Jr is crisper. Easy connection. The reason I did not give a five stars is because when I saw them they looked a little cheap . PACKAGING: I appreciate that the shoes come with plastic forms, so they maintain their shape with storage and travel. Much better than those plastic ones.
