Known as toggles, these are the equivalent of the Japanese netsuke, and some researchers say these predate the netsukes. First photo - a freeform piece of wood with a knot, shaped a bit and drilled. This would hang at the bottom of the cord and prevent the inro (container) from pulling out from under the belt (Fred, correct me if I don't describe this accurately). I have searched for quite some time to find examples of these that were typical of those used by country people or farmers, and lo and behold Joe Loux had them at Gem Mall. The first one is 2 inches (50mm) long, the patina is stark-raving gorgeous. The second photo is a more sophisticated example, carved as a monkey (35mm x 30mm), also with rich patina. Since these are ornaments which are perforated and hang from string or cord, it seems they should be acceptable in this forum.
