The pieces are of course milled from solid wood, and the solid maple tops contrast very nicely with the walnut accented supports.45 copies made for sale, each signed and dated.Combined shipping available

"Gentleman Crocodile" is, by far, the cutest Karakuri box I have seen!  It is crafted by the very popular Yoh Kakuda of the Karakuri Creation Group.  It was designed by Kakuda for his 2015 Karakuri Christmas gift, and then redesigned for a slightly larger size in 2022.  The box is made from 4 woods: magnolia, walnut, chanchin, and keyaki.
