Since there is no receiver, I have not confirmed its operation. Please be aware of this. It is relatively clean. Please check the photos. Please use it for parts, etc. Due to the above reasons, we request no cancellations or returns. In addition to this, I am selling mouse and keyboard related products, so please take a look. Bulk purchases are also welcome. Anonymous shipping (free shipping) will be used. It will be shipped via Yu-Packet Post (mini). Due to thickness restrictions, the packaging will be simple. Contact may be delayed due to travel or work. Also, shipping may not be possible on weekends, holidays, Golden Week, year-end and New Year holidays, and Obon. Please be aware of this if you are in a hurry. Thank you. (Management number 1)
