[Prevent Damage] These carry-on suitcase lids are made of food-grade silicone with a unique zigzag pattern, providing extra protection for the wheels, reducing noise when rolling, protecting hard-shell suitcase wheels from rough surfaces during travel and wear, and protection from moisture and other harsh elements. [Anti-falling design] The suitcase wheel protective cover features an upgraded anti-falling design. When installed on the suitcase wheel, it expands the coverage of the protective cover and effectively prevents it from falling off during rolling. The thickened sawtooth pattern of the wheel cover is more wear-resistant, helping to keep your large luggage secure and durable. [Easy to Use] Using the spinner luggage cover is simple compared to finding and replacing the entire wheel. Luggage wheel covers are suitable for 28-inch and other 8-wheel suitcases and fit wheel diameters between 1.9-2.7 inches (5-7 cm). Easy to put on and clean. Save money and hassle by using wheel covers to protect and extend the life of your luggage. [Easy to Install] Our luggage wheel covers are easy to install; simply place the protective cover along the edge of the wheel. [Larger Wrapping Area] Unlike other luggage protectors, our wheel covers offer an increased wrapping area, which helps prevent them from falling off. [Tire Pattern Design] The tire pattern design increases wheel friction and reduces noise caused by wheel sliding.
