Slide cushion rubber for trumpet / cornet. This is a set of 8. *This is the "thin" type. (Same "thin" type as in the photo.) These are used to eliminate the "clack" sound when sliding and returning the 1st trigger or 3rd trigger, but they also improve the appearance. Normally, 4 are used for a trumpet and 2 for a flugelhorn, but since these rubbers are starting to harden slightly, we are offering a set of 8, including spares in case of damage. If, by any chance, all 8 are damaged, please contact us and we will exchange them for 4 "thick" ones. If anyone is interested, please let me know. Thank you. m(_ _)m
