Boron is a moderately difficult puzzle that displays like a piece of sculpture once it's solved. The 12 pieces are made with contrasting hardwoods and precision-crafted in our North Carolina workshop. Its interlocking nature means that several pieces have to shift around to release the first piece. This puzzle is a lot of fun and a great addition to anyone's collection, beginner or advanced. Boron is delivered disassembled.
