Thank you for viewing. It's effective for training muscles in areas that tend to weaken due to daily life or childbirth. We'll help you become aware of muscles that are difficult to consciously engage. It's a daily practice, so please carry it with you and use it anytime, anywhere. This is the latest improved version, so the quality has been upgraded. Price is not negotiable. Purchased in October 2025. Brand new and unused. I took it out of the box to take photos. To those who have commented... I may be slow to respond.
