Cork-back coaster is a small, flat item used to protect surfaces from the moisture and heat of beverages. The bottom layer is made of cork, a natural, eco-friendly material harvested from cork oak trees. Cork's lightweight, durable, and non-slip qualities prevent the coaster from sliding on surfaces and protect furniture from scratches. It's also moisture-resistant and can absorb slight condensation without damage, ensuring the coaster stays effective over time.
