This is an ab machine that allows you to train your core simply by sitting and swaying. I purchased it a few years ago and only used it 4 or 5 times before storing it in a bag at home. I have confirmed that there are no noticeable scratches or stains, but please forgive any oversight as it is a personal check. Please assess the condition based on the photos. Please consider purchasing if you understand that this is a used item. Thank you. ■Size Width: 309mm Depth: 615mm Height: 390mm ■Weight: Approximately 3.7kg ■Weight Capacity: 100kg ■Materials: Polyurethane, Iron, Polyester ■Color: Green ※Instruction manual and original box are not included.
