These are now my go-to gift-in-a-hurry solution. I can cut out one of these boxes and assemble it in less than a half hour and the recipient is always terribly pleased and impressed. Because acrylic comes in so many different colors, the possible combinations are nearly endless. I have perfected this design so that the lid fits in place with a satisfying "snap" and is held securely - though is easily removable. The boxes measure approximately one inch tall and 2.25 inches square.
