Thank you for viewing! Thanks to you, many customers have purchased from me, and I have a track record of high ratings. I am confident that my rubber is the most affordable and has the highest holding power! The photos show the KUN rubber after replacing the deteriorated rubber. The tubes are made of American rubber (raw rubber). Sold in sets of 4. If you would like multiple sets, please let me know in the comments before purchasing. This product is for 4/4 size KUN old type claw rubber replacement. (Not genuine) *Unsure if genuine products exist I do not know if it fits other fractional sizes or shoulder rests from other manufacturers. If the rubber deteriorates, your precious violin may slip and fall, so I recommend replacing it early. It is slightly long, or cut just right, so cut off any excess with scissors. It will be shipped by regular mail, but I am not responsible for any postal accidents. (Regular mail is not delivered on weekends and holidays) Due to Japan Post's circumstances
