Start off with a clean slate during your next ad campaign! The Round Slate Coaster Set provides 4 coasters that include feet on the base to place on coffee tables, desks and more. All the coasters will feature imaging inside the 2 1/2″ x 2 1/2″ imprint area and fit beautifully in the onyx presentation boxes. Due to the natural material being used, some variation may occur from piece to piece, and square versions can also be ordered. Provide this promotional quartet at your next trade show event for gifts they won’t soon forget!
