Inflatable boat (inspection welcome)

Purchased new in late October 2025 for sea fishing (just over 30,000 yen including shipping). However, I changed my mind and decided to buy a resin boat, so I'm selling it without ever having launched it.
When I inflated the boat to check how easy it was to handle, I loaded it onto the bed of a mini truck. Some dirt from the mini truck's rubber mat got on it in a few places.

This item was purchased online, and there was no instruction manual from the beginning.

Accessories:
3 floorboards (resin), 1 seat board (aluminum), 2 oars. Additionally, there are 2 air cushions, possibly for sitting on the boat's bottom or for back support (I'm not entirely sure), a foot pump (it's a bit flimsy, but it can inflate to some extent), and a repair kit for punctures. I will include everything I received when I purchased it.

I recommend using an electric air pump with a pressure gauge that fits the air inlet/outlet shown in the second photo.
