⚪︎Viva La Musica Violin Shoulder Rest VIVA FLEX M (1/2-1/4) blue ⚪︎M size for 1/2-1/4 violins The angle of the legs is adjustable and rotates 360 degrees. The legs are foldable (collapsible). I no longer need it because I upgraded sizes. It has been used to some extent, but I think it will work perfectly fine.
