Here at Phoenician we realize that some patients tend to remove the lid after grinding and tap it against the storage section of the grinder in order to congregate the ground herbs to one side, making the removal of the ground herbs easier. However, this can cause unnecessary wear on the grinders exterior most commonly resulting in unsightly dings and dents. We are now proud to offer a new accessory to our grinders: Bumper Rings! These soft rubber rings can be applied to the outside of the lid and act as a cushion between the metal surfaces. They fit snugly into the existing lobe knob grip design for a clean well fitted look. We make Bumper Rings for all sizes and configurations of our grinders. Each package includes 2 rings. These rings require no tools to install and can be removed/installed very easily.
