Thank you for viewing! (^_^) This is a fishing platform with a backrest from Sansei Seisakusho, designed for crucian carp fishing. The seat is 30x60cm, and the height is adjustable in stages: the short legs are 21-35cm, and the long legs are 27-47cm. When stored, it's 32x32cm, 7cm thick, and weighs 3.5kg. It's a fishing platform with a backrest that's convenient to carry and compact (it looks like it would fit in a fishing bag). The legs are fixed by inserting them and then securing them with butterfly screws. I think it's well-made. It's a used item, so there are some minor scratches and rust. For attaching a vise, I'll include a long, handmade, insertable horizontal bar that can be stored. Please make your judgment based on the photos, and please understand that this is a used item. Please refrain from purchasing if you are overly concerned about condition. Free shipping. How about it? (^_^) #CrucianCarp #WildFishing #CrucianCarp
