Asuna XL 藍色運動球附充氣幫浦

The pump that comes with it is a lifesaver—inflated the whole thing in a couple of minutes without breaking a sweat. I’ve been using it as a desk chair during the day and for core work in the evenings, and it holds up nicely without losing air.

It’s big enough that I actually use it as my desk chair sometimes, and the blue color makes my home office feel less dull. The included pump got it fully inflated in a few minutes without me breaking a sweat.

The ball holds air perfectly once inflated—I’ve been using it as a desk chair for two weeks and haven’t had to top it off. The included pump makes setup surprisingly easy, too.
