As a basis, a good solution. In practice, it's a bit lame. It's printed on only one side, so it depends on how you have your library designed, currently I have it so that I can only see the wood, because the printing is on the other side. It would be nice to have printing on both sides in the new version. The thickness could be thinner and maybe I should have gone with plastic. It creates unevenness. What I didn't notice when ordering, one separator is for 2 letters, my mistake. So I recommend it for a smaller collection and think about how you will use it. Probably ideal for a store-type collection when you have a bookmark from above, i.e. vertically. And I would appreciate the additional purchase of the letters themselves. The processing is otherwise clean and in order.
