Thank you for viewing. This is a set of two factory-b tatemadai (fishing table) for sale. They were used inside a dome boat. The difference from the genuine product is that magnet plates have been attached. There are minor scratches from use, but there are no malfunctions. Details: Height adjustable in 4 stages * Each dimension increases by 30mm when ice spikes are extended. 1st stage: 40mm (stored) 2nd stage: 195mm 3rd stage: 240mm 4th stage: 280mm Thank you. #WakasagiFishing #Tatemadai
