1. Practical Function: Just paste the stainless steel universal wheel on the bottom of the box, and the heavy box can be easily moved. The silent wheels are stable and quiet, won't scratch the ground, are not easy to shake when pushed, and can better disperse the force and load. There may be a slight color difference between the object and the picture due to lighting. Please wait for 24 hours after pasting before use. 2. 360 Degree Rotation: The mini paste pulley can slide to any angle without limitation. It is completely silent when in use and is suitable for makeup storage, kitchen, table top, bedroom, living room, and flower shelf storage. Shipping may cause the wheel not to turn smoothly. Please roll the wheel by hand to make it turn smoothly. It may leave marks on the table. The caster can bear a load of no more than 5 kilograms. It is not recommended to use casters on a wooden floor or quartz surface to avoid scratching the surface. 3. Quality Material: Storage box casters are made of strong ABS material and small steel balls, sturdy and durable, firm and wearresistant, and can move heavy objects easily without pressure. Note: Sliding on the wood surface may leave tracks. 4. Easy to install: Simply peel the film on the back and firmly press it onto the smooth surface. Please wait for 24 hours before using. The smooth pulley makes it easy and convenient to place heavy objects.
