Two-wheeled ab roller with high stability and quiet operation!! ◾️FEELCAT ◾️Abdominal Muscle Roller ◾️Weight Capacity: 200kg ◾️Materials: Stainless steel pipe, ABS resin, EVA material ◾️ Two-wheel design, high stability, ultra-quiet specification I purchased this late last year and used it a few times, but I started going to the gym at the beginning of the year and stopped home training to avoid overwork, so I'm selling it. I threw away the box, so it only includes the main unit and the knee protection mat. The condition is good because it was used for a short period, but there may be some signs of use, so please refrain from purchasing if you are sensitive to such things. Please understand that this is a used item before purchasing.
