Eureka 515056″ Huzzle Cast Coil Puzzle

Warning: Not suitable for children under 3 years. For use under adult supervision
It appears like a box-like lump with a hole in it, but is actually comprised of 2 coiled up virtually identical pieces. You must try to take it apart by sliding and rotating the pieces. Although the pieces are angular in shape, they can be rotated in unexpected ways, making their movements quite intriguing. The theme of the puzzle is “Loops”. Designed by Edi Nagata of Japan.
not appropriate for children under the age of 3
