This is a used Armstrong WING 4.5m2 wing, a well-known high-end brand in the wing foil industry. Due to numerous simple repairs made by the previous owner, this item is being sold as completely junk at a bargain price. Suitable for: * Beginners and freestyle land training * Parts for the center strut bladder * Repair practice or research material The specified air pressure is 7psi, but I was afraid of punctures and only inflated it to 3psi. There are no areas that immediately require repair for land practice, but there is a tiny air leak in the bladder near the right-hand side of the leading edge air valve. Please understand that this is a used, junk item (strictly prohibited for use on the water) before considering a purchase. 【Brand】Armstrong 【Condition】Used, with scratches and dirt, no accessories 【Size】4.5m2 Thank you for your consideration. #WingFoil #FoilBoard #WingFoil #WSF #Foil #Surfing #Foil
