Bumper Specialties, Inc. only makes self-adhesive polyurethane bumper feet. This allows us to focus solely on perfecting the process. They are made of 100% polyurethane and have a very aggressive adhesive. These products do not contain plasticizers, oils or fillers, and they will not mar, scratch, or stain any surface. They are kiss-cut and can simply be peeled off by hand, enabling the bumper to be placed where protection is needed.
