Four red rubber rings. Removed from 5kg dumbbell plates from IROTEC. These rubber rings are designed to be attached to iron plates, preventing floor damage and reducing noise. I removed these from iron plates I purchased on Mercari. If the rubber rings have deteriorated over time, the rubber can easily tear just from the force of removal, but these still have good elasticity and can be used again. They are used, so there are some scratches on the surface, but they are not a problem for use. They are specifically for IROTEC 5kg plates, so please be aware that they are not compatible with different weights or plates from other companies. - Color: Red - Material: Plastic - Shape: Ring - Quantity: 4 pieces Thank you for viewing.
