This is a small sandalwood fan frame imported to Japan before the war. It's quite old, and the inscription reads "Enko 4th year, February..." I bought 10 of these in the 1950s for about 8000 yen each, and this is the last one. Unfortunately, the tip of one of the ribs is missing. The longer fan is also from the 1950s. The tip of one of the ribs is missing on this one too! They were expensive, so I believe the material is of good quality.
