FLEXTAILGEAR TINY PUMP Portable Air Pump

Purchased in the summer of 2025, I intended to use it for inflating air mattresses while camping, but found manual inflation was faster, so it has been stored with almost no use.
There are no noticeable scratches, but the characters 入 (in) and 出 (out) written in permanent marker are faintly visible.
Also, the included storage bag was too flimsy, so I have put it in a different bag purchased from Daiso.
