Drink Coaster Ship Saginaw Lower Lakes Towing Ltd. Great Lakes Nautical Gifts & Collectibles For Boat Fans. Great Lakes Freighter Photography. Our Coasters pop with vivid color, making them that perfect unique gift. Bring back that special place in Michigan with one of our many beautiful tile products! Images are high resolution and imprinted deep into the tile, they will not fade or peel. They can hold heat up to 400 degrees, making them perfect for coasters & trivets. They also are stain resistant and waterproof and can be washed with any cleaner. All coasters and trivets have cork backings. Due to cork backings, we do not recommend washing in a dishwasher. All coasters can be used with regular tile work and would make a great freighter theme backsplash. Hope you enjoy the photos!
