The Artino Comfort line of shoulder rests are made of a high-strength plastic and have a firm, yet comfortable foam pad. There are three sizes to choose from, fitting 1/8 - 1/4, 1/2 - 3/4, and 4/4 Violins. The rest is ergonomically designed to fit the contour of the shoulder, while a hi-tech synthetic skid-proof gripper provides comfort and prevents slippage. Featuring a wide range of width adjustments for personal preference, this essential accessory is a great choice. Make sure to choose your size from the options.
