Thank you for viewing! Used item: Caster stoppers Plastic, 8 pieces Large ones: Diameter: 6.4 cm Hole diameter: 3.8 cm Small ones: Diameter: 5.6 cm Hole diameter: 3.8 cm *The hole diameter is the same for both sizes. These are used items, but I think they are still usable. There is some aging due to wear and tear, so please take a close look at the images and purchase only if you are satisfied. Thank you!
