This Guarneri style chinrest is a drop-in replacement for almost any violin or viola.
The printed chinrest is combined with standard metal mounting hardware with cork backing. This chin rest is not annealed for high temperature resistance, so if it is left in the sun it could possibly loosen (unilkely, though). Just keep a chinrest wrench or paper clip in your case so if it loosens someday you can tighten it.
Anyone can enjoy a colorful chinrest, but this color combo is specifically designed to match the colors of a rainbow Pride flag. Mount this chinrest on your fiddle as a reminder to us all that all people deserve to live full lives with dignity.
