NE LavaStone Coaster Maru Green 1 Piece Diameter 9cm Thickness 1cm Absorbent Lava Stone Asbestos-free Quick-drying Round Small Plain NEO-267M-GR

Size (approx.): Diameter 9cm × Thickness 1cm Weight (approx.): 55g Material: Lava stone (volcanic rock), plant fibers Country of origin: China It quickly absorbs the surface water droplets that form when cold beverages are placed in a glass, thanks to the excellent water absorption properties of volcanic rock. The coaster will not stick to the glass. It naturally dries over time, requiring no maintenance. The porous structure is formed when magma erupts near the surface, and the reduction in pressure causes volatile components, such as moisture contained in the magma, to turn into gas, resulting in a foamy solid structure with countless pores.
