Trying to figure out what says here and what this artifact is
This appears to be the end piece of a folding fan. Maybe the rest of the fan is missing?

The characters should be read from right to left:
金澤 jin1ze2
櫻谷特製 ying1gu3 te4zhi4

金澤 is the Japanese city Kanazawa. 櫻谷 means "Cherry blossom gorge" and would be pronounced "Sakuraya" in Japanese. This is probably the name of a place or a company. 特製 means "special product of".

So presumably this is a special product of Sakuraya in Kanazawa. While the names appear to be Japanese, these words would mean exactly the same thing in Chinese.
