Thank you for viewing. MASPRO UHF.BS.CS Booster UBCB35 MASPRO Booster Power Supply for UBCB35 BPS5B Used until the end of November, but I am selling it because I bought a new one. There is rust on the back, but I think it does not affect the use. Please understand that this is a used item and has been inspected by an amateur. This is an item for sale during the Mercari Festival period. If you have any questions, please ask before purchasing.
