Natural raw volcanic rocks are hand-cut and ground into oval shapes. It is inevitable that a small amount of powder will be hidden in the bees' eyes after cutting. Use after cleaning.
Volcanic stone is characterized by many pores, light weight, high strength, heat preservation, heat insulation, sound absorption, fire prevention, acid and alkali resistance, corrosion resistance, no pollution, no radioactivity, is an ideal natural green, environmental protection and energy saving raw material.
