Having never seen an antique charm of this design before, it is possibly rare. I believe it is called a KOBE charm made in Japan, but I am no expert on this item...However, I will list what I see and have provided quite a few views. It's an adorable tiny size of a cigarette and a dangling case. They both have painted detail (the case on both sides) and the case appears to have Mother of Pearl inlay. The case opens to reveal 3 teeny carved dice. This is one gorgeous vintage charm!! It measures approx. 2 1/2 in. long including string x 1 1/8 (cigarette length) and 3/4 in long (case). Excellent condition.
