Highly recommended for students: beginners learn to hold violin properly with the chin instead of the left hand. Reduces chinrest irritation and unnecessary fatigue. Strad-Pad rests directly on the chinrest, not the violin. It ends perspiration annoyance and is a great relief for men with beards. Easily detachable with its velcro strip and may be washed. A perfect gift idea for violinists and violists. Made in USA. The Strad-Pad is available in two sizes: Regular (10.5cm - 4" at widest point) and Large (13cm - 5" at widest part). Both can be easily cut down to size with scissors to suit the size of the chinrest, especially fractional size instruments.
