Review on Unleash Your Puzzle Skills with the Original 3D Crystal Puzzle Skull by Etai Gopala

BUY IT! I bought 2, one black and one clear. This is by far the coolest type of puzzle; my 11 year old loved it. Very cheap fun and now we have two identical skulls that teenagers think are cool. As for the difficulty of "Level 2": adults - 1 hour, 11 year olds - 2 hours. without falling apart. You have to turn the key slot to disassemble the parts. Possibility of disassembly/assembly. Each piece is unique and sits very well and firmly. Good quality, no junk. The assembled size is about the size of a tennis ball.
