This is a Joy-Con controller specifically for the Nintendo Switch fishing game, "Fishing Spirits." The owner purchased it but apparently didn't enjoy it, so they tried it once and then stored it away. (They've never actually gone fishing, so they didn't know how it worked.) According to the instructions, once assembled, it seems you can't take it apart, so it will be packaged as is and shipped with the instruction manual. If you need the box, it can be folded and included. Please let me know.
