Thank you for viewing my product. This is TAMA cymbal hardware. How about using it for unit expansion? (Model number unknown) It has been stored in a warehouse for a long time, so the condition is as expected. The items in the photos are all that are included. Please refrain from purchasing if you are expecting a new, unused level of condition. There are minor scratches, but overall, it is in good condition. Please check the photos for details. Please note that returns are not accepted. Also, shipping will mainly be on weekends, so please be aware of this. Thank you for your understanding. I am also listing a lot of other drum hardware. Please take a look if you'd like. That's all.
