★ [Wireless Receiver] [Domestic Genuine Product] ★ Condition: Used This was used by my grandfather, and I'm not quite sure how to use it, so the operation hasn't been checked ( *˙ω˙*)و Good! There's no noticeable damage! It seems to have a built-in magnet, as they stick together when stacked ( ᐛ ) I wonder if you're supposed to use them stacked? ★ This is a one-of-a-kind item, so please make your decision quickly ★
