Felt coaster features
The main function of the coaster is water absorption. Because the water cup is a water-absorbing tool by nature, it is unavoidable to spill it out during the movement. Therefore, a coaster with good water absorption can ensure the cleanness of the table.
Due to the compact density of the felt, there is more friction on the tabletop than other types of coasters.
Felt has a very good thermal insulation, can guarantee the minimum temperature of the cup to the desktop, keep the material of the desktop material is not deformed, and the water temperature in the cup will not change too fast.
