Replacement rubber feet for violin/viola shoulder rests. Made of silicone rubber. Cut to approximately 40mm. Sold in sets of 4. Can be used as replacement claw feet for old-style KUN shoulder rests for 4/4 size violins or violas. The second image shows the product attached to a violin shoulder rest. Please note that we do not know if these are compatible with fractional size violins or shoulder rests from other manufacturers besides KUN. Silicone rubber is said to have less impact on the instrument's finish and to be less prone to degradation. However, it is also said to come off more easily compared to natural rubber. Please refrain from purchasing if this is a concern. (Personally, I have never felt that they come off easily.)
