Kalmar Home's Acacia Wood 4 Piece Puzzle Shaped Coasters Set is a beautiful way to protect your surfaces from unsightly water rings and heat marks. Each coaster is meticulously cut from high-quality, sustainably sourced acacia wood renowned for its natural durability and beautiful grain patterns. When the four coasters are joined together like puzzle pieces, they seamlessly interlock to form a heat-resistant and sturdy trivet. The rich, warm tones and distinctive grains of acacia wood create stunning pieces complimenting any décor style. We recommend hand-washing with mild soap and warm water to maintain its beauty and integrity for years to come. To preserve the wood's natural luster, occasional oiling with food-grade mineral oil is recommended.
