This is a batch of 24 assorted cube-shaped dexterity puzzles. Some duplicates, which I've grouped together in the photo. One cube is scratched up, the rest are in very good condition. One has glitter embedded in the plastic (came that way) to make it more appealing to people who don't like dexterity puzzles. Each cube is 1.5" in size.
