Purchased in March for 9600 yen, used a few times. The double-sided tape on the back has not been used, so you can attach it to the wall with new adhesive and screws. Using the unused Velcro straps for fixing will likely make it even more stable. You can connect via Bluetooth and do boxing exercises with your favorite music. Operation is not a problem. Charging is via USB-C. After getting tired of boxing exercises, I used it as a wall-mounted Bluetooth speaker. How about it for stress relief? (^^) When you hit it at the moment it lights up, it makes a satisfying "bish" sound, and if you miss, it makes a disappointing "byooon" sound (lol) You'll be sweating by the end of a song, so I think it's good exercise♪ Size: 40cm x 40cm, Thickness: Approximately 7.5cm Gloves for adults and children included.
