TWO SIZES: We offer our diatomite tray in two different sizes to cater to your specific needs. The smaller size measures 3.15 inches by 3.15 inches by 0.35 inches (8cm by 8cm by 0.9cm), while the larger size measures 6.3 inches by 3.15 inches by 0.35 inches (16cm by 8cm by 0.9cm). Each pack includes 1 of each size, providing you with ample options for various purposes. MATERIAL: Made from natural diatomaceous earth and plant fibers, these diatomite coasters are highly absorbent. They quickly dry out, leaving your countertop neat and tidy. Our materials make the tray incredibly durable even with daily use. ANTI-SLIP PERFORMANCE: The design of our fast-drying stone sink caddy prevents sliding and skidding and improves the contact surface between the coaster and the air. These non-slip mats are long-lasting and ideal for daily use. EASY TO CLEAN: Our absorbent table mats are simple to clean. Just rinse them under running water and wipe with a damp sponge. Let them air dry, and they'll look brand new again. VERSATILE AND PRACTICAL: Our diatomite tray is not just limited to cups. These absorbent pads are ideal for a variety of uses. Whether it's as a mat for soaps, makeup bottles, or even as a coaster, they deliver exceptional water absorption. Keep your table or countertop surface dry and protect it from potential water damage.
