Back pain? Neck pain? Are you a yogi? These Chirp Wheel+ wheels are the perfect thing for you! Purchased during the pandemic for use to relieve repetitive use back pain from working in a lab. These wheels are perfect for stretching and relieving the worst pains. Comes with its own carrying/storage bag and the wheels nest very nicely inside of each other. Used only a handful of times and selling because my husband and I are moving and are trying to downsize.
