LandSup Crazymini Wooden Balance Board for Surfing and Core Training

Purchased about 2 years ago.
Used a few times indoors, but no longer needed, so I am selling it.
Comes as a set with the box, the board, and the air pump. Unfortunately, the instruction manual is not included.
There are no noticeable scratches or dirt, but please check the images just in case.

I am open to price negotiation. Please feel free to discuss.

◼︎LandSup Crazy mini
◼︎LandSup New Sensation Training Board

Land means land, and Sup stands for Stand up paddle.
This is the first balance board born in Japan with the concept of experiencing the sensation of Sup on land.
Ride the board to create an unstable state and find your body's axis and your core, which tend to become unstable in busy daily life.
This is a balance training board that allows you to feel the gentle touch of wood while returning your mind to a neutral state and working on your core and inner muscles.
