■ Product Description Are you worried about "the noise of the casters," "getting the room dirty," or "the casters wearing out quickly" when using your important suitcase for travel or business trips? This product significantly reduces the rattling noise of the casters when moving, allowing for quiet movement. You can rest assured when traveling at night or early in the morning, or in places where sound easily echoes, such as apartments and hotels. Simply removing the cover at the entrance prevents sand and dust attached to the casters from entering the room, keeping the room clean and tidy. The caster covers reduce friction, prevent the deterioration of the casters themselves, and allow you to use your suitcase for a long time in good condition. ■ Materials, Size, Color, Quantity Material: Silicone (elastic) Size: For 5-8cm double casters only (not compatible with single casters) Color: Black Quantity: 8 pieces (for one suitcase) ■ About Shipping Free shipping.
