Golden Piano 3D Puzzle
If you like it shiny, choose this metal-based 3D puzzle. It comes with one sheet (4.3 x 8.3 inches) of golden-colored stainless steel from which the 14 pieces can be pushed out, and with easily understandable picture-based assembly instructions. Part of the challenge is to bend the pieces into the right shape before putting them together. The final product has the dimensions 2.6 x 2.2 x 2.8 inches and weighs 6.4 oz.
For ages 8 and up. A pair of tweezers is recommended for assembly. No glue required.
