Good quality. Nice to handle. Looks like it can't be solved. Sublime solution. Must get others like this.
Have 6 grandsons & 4 sons. This was the perfect gift for them!! (I got a different puzzle for each.) I was happy it was a big hit!!!
Thank you for sending me the one and only real Hanayama Key 1! It took me a pretty long search to find, because at many places it was sold out or out of stock! I really enjoy this number one key version I'm certainly going to put another order onto this site in the future!! 😊😊😁😁
