Too short for some of my store-bought reading glasses. Made of paper and cardboard. Feels like they will not last nearly as long as ones from the optometrist before the paper attachment between the two clamshell halves begins to disintegrate. Color is already scratched off from a divider in the same drawer. BUT, they do work, and I have my everyday glasses in them each night, the color being easy to see. And a SMALL pair of sunglasses in one in a pocket in my purse. They helped me not keep spending an inordinate amount on glasses! and the colors are pretty. So I am happy. They are a lower price point, and so you get what you pay for.
