UNION CONTACT PRO White M size (24.5-27.5cm) 18-19 Season Model Snowboard Bindings Purchased used on Mercari, but it did not fit my current board, so I did not use it. Due to the white color, dirt and dullness from age are noticeable, but there are no spring failures and it is still usable! I bought it to try UNION bindings, but since it didn't fit my board, I am selling it. Please comment if you have any questions. *Below is a copy of the manufacturer's description. The popular model that has gathered absolute support has further evolved while keeping its concept. It is incredibly light and has excellent shock absorption. This model is recommended for those who want to finely control the board while feeling the board's flex.
