Melting Blocks Puzzle (Redstone Box)

This is a really attractive puzzle. Comes with an all hardwood box and sliding lid. Embedded into a hold area on the lid is a red block, the “Redstone”. If you remove the lid you will see that the box appears to be full to the top with 8 pcs. The puzzle comes in the unsolved state. Your goal is to insert all 9 pieces in the box so that you can slide the lid back on. This of course is the most important point, since the outer box is slightly taller than the lid. Seems impossible, but of course it can be done. It really is a difficult puzzle! Comes with clear instructions. Box measures about 4 1/2″ x 3″ x 2 3/4″ high.
