Huzzle Puzzles by Hanayama of Japan.
Huzzle Puzzles are disassemble and re-assemble puzzles (disentanglement challenges). All the Huzzle Puzzles are made from cast metal (alloy). None of these puzzles are suitable for children under 8 years. Huzzle Puzzles are ranked according to difficulty, from 1 = easy to 6 = Grand Master (which is seriously challenging!).
