This is the store to go to for sanshin stuffs, especially from buying overseas. This store takes great care in packaging the items they sell. They even leave a note on the package, explaining that the item is delicate instrument, so handle it with care. And they package outer side of the box too with bubble wrap. I've never seen a store with such care. Also, it's kind a nice that they give Okinawan charm for protection for the item. It's very cute.
There are bad sanshin sellers on ebay, I had to learn the hard way, but after discovering this store, I'm going to buy sanshin parts and accessories only from here, cuz I completly trust this company!
