A very nice example of the line of charms that were made in Japan of carved and painted ox bone and that bear the distinction of having a secret compartment that opens to several very tiny fully removable dice. This one is a very traditional and classic Japanese Medieval item, an Inro, which is a bag that was hung from the obi or sash of a Japanese kimono and carried by both men and women. The inro was usually made of lacquer and had a carved round netsuke made out of ivory that hung on knotted rope and weighted the bag at the end. In the center, separating the inro from the netsuke was an ojime or bead. This well executed inro charm is decorated to represent the decoration on lacquer, which it is ornately done in black and gold paint on the front and only gold decoration of long leaves or grasses and a bamboo stalk on the back. There is an authentic knotted string with the netsuke at the end and it even has the ojime bead in the center dividing the two. This bead was used to tighten the bag or loosen the bag when slid to allow the wearer to remove items and then to tighten it so that it was secure. The netsuke at the end is painted as they traditionally are and there are colors of red and blue in the decoration. The back of the charm has a notch to slide open the back to reveal five tiny dice that are perfectly formed with red and black dots. Often only a few of these dice remain but it appears that these have never been removed as they are in a perfect straight line inside of the hidden compartment. The charm is in excellent condition with none of the beautiful painted detail worn. It measures 3/4" long and 9/16" tall without the hanging netsuke and 3/4" with it.
