Macaco is not only fun for its elasticity, but also suitable for balance training and core strengthening due to the finely knitted lines that create flexibility. • Designed to provide a natural full-body workout while you're having fun playing. Used about 3 times. There are no noticeable stains on the lines. Please check the ratchet part in the photos. No bag. There are two pieces of patching cloth. The instruction paper is folded. Thank you for your consideration.
