The Karakuri Small Box Gravity puzzle box is a nice, special edition of the small box series of wooden puzzle boxes.
The bottom of the box can be pushed in on a spring but how to open the box will require some thinking.
As always beautifully made by Osamu Kasho from Walnut, Wendge and Mizuki.
The Small Box Gravity puzzle box measures 60 x 60 x 50mm with an internal storage space of 43 x 43 x 24mm.
The solution is provided.
