This is a turn board used for practicing turns in ballet and figure skating. It's a training tool for developing a sense of balance for pirouettes and spins. It's lightweight and compact, making it suitable for self-practice at home. It enables smooth rotation and supports the strengthening of correct posture and core. It can be used for turn practice in various dances, not only ballet, but also rhythmic gymnastics and social dance. Used only a few times indoors. Thank you for looking.
