Hanayama | Coaster Hanayama Metal Brainteaser Puzzle Mensa Rated Level 5 - 75*119*45 mmSerhiy Grabarchuk is a famous Ukrainian puzzle designer who lives in Uzhgorod. The puzzle depicted on the piece of drawing that he sent me looked like a strange adornment weaved into a coiffure design. If you put a glass carefully onto the completing puzzle, it becomes, indeed, a coaster. Using this when serving drinks to guests will on doubt create stimulating conversation. The theme is Coiffure.
