This is for a pair of bumpers - one large and one small - to fit our regular Troemner as we have sold it for about a decade. The base of the large bumper is about the size of a dime. The material is never-age super soft. The color is black. We do not guess whether our bumpers fit percussors manufactured by other companies.
