Plexiglass place markers

These super fun plexiglass (? not sure if that is the best word for what they are, but they are not glass, and they are way nicer and heavier than plain ol' plastic) blocks were used to mark place settings at a dinner in LA. (The brown you see behind the names is protective paper that peels off, which I chose to keep on for transit out west.) But aren't these cool?! I would totally keep mine for a paperweight. I'm used to using skinny sheets of plexiglass, but these were a delightful alternative.
