【Abdominal Exercise Machine】 This is a Wonder Core Smart with added twist exercise functionality. I used it a few times, but stopped using it after a while, so it has been stored at home. Instruction manual included. As shown in the second photo, there is some slight dirt, but it does not affect use. The sponge parts are also clean, and it is in good condition with no other stains or tears. Please understand that this is a used item and consider purchasing it. I have lightly wiped the entire item with alcohol. It will be wrapped in bubble wrap with cushioning material and shipped in its original box.
