This product comes in three different weights, namely 500g/㎡- 600g/㎡- 800g/㎡. The three values correspond to the square weight of the product (which can be simply understood as thickness, the higher the value, the thicker it is, but it is not used as a reference for thickness data). All three are made of high-density coral velvet and have strong water absorption! It is suitable for car washing, floor cleaning, furniture cleaning and other dual-purpose uses for both home and car! Due to the issue of cutting wear and tear, there may be a slight fluctuation in the weight per towel.
