This Thanks For Helping Us Grow Coaster Set is a fun and unique way to show your elementary school teachers, staff, and volunteers how much you appreciate their dedication to your school and students. The set includes two 4" diameter natural poplar wood coasters, each featuring our "Thanks For Helping Us Grow" design. The coasters come packaged in a reusable burlap bag with drawstring closure. Each coaster is unique in structure, resulting in size and color variations. Repeated use creates a weathered patina, adding to each coaster's unique character.
