Hi, I recall recently buying a product similar to this but wasn’t a best quality shime which I had to tention. Though I had no problem with this, I wondered what happened to it as it was a good $300 apart from each other.

Best quality one is made of the best material and has higher quality than a shime you bought from us. Best quality shime is with high quality drumhead and body, which is made of keyaki (Japanese zelkova wood). The sounds produced are the best and deeper.
