The screws on page 3 were defective from the start and were a little loose. We used tape on the back at home... There were no problems with the sound. Currently, there are not many batteries, so we plan to ship without batteries. The battery cover is difficult to open, so we were able to open it with the adhesive force of tape. Thank you for your understanding. We plan to ship via Yu-Packet Post Mini. Other Notes: * We inspect the items, but they are stored at home. Regarding the condition, there may be oversights. Please refrain from purchasing if you are concerned about this. * We cannot accept claims after a purchase, so please understand this before making a transaction. * Shipping will be via Yu-Yu Mercari Bin or Raku-Raku Mercari Bin. * Please forgive any wrinkles due to storage or packaging. Thank you for viewing.
