Even though this wrist brace was lame because of having a thumb hole on both sides, it has turned out to be most helpful for my ganglion cycst of the 2 or 3 I've tried since buying this one. Of course, it's not in the stores anymore, but I tracked it down. It turns out that the original wrist brace had a tag that said "B306". That is this Beige 306 brace:

I only figured out recently that the metal bar inside was intended to be removable!
