Get creative with these blank sublimation coasters that are perfect for DIY projects and personalized gifts! This pack comes with 150 circular coasters that fit most standard car cup holders at 2.75 inches in diameter. Made from neoprene with a special heat transfer layer, they're ready for you to print your own designs, photos, or patterns using sublimation printing. The process is straightforward - use a heat press between 356-428°F for 20-60 seconds to transfer your artwork permanently. They're not just for cars though - use them in your living room, office, kitchen, anywhere you need to protect surfaces from drink rings. The material is absorbent, heat-resistant, and has a non-slip quality that keeps them in place. Perfect for creating unique gifts for holidays, birthdays, housewarmings, or promotional items for your business. With 150 pieces, you've got plenty to experiment with and create coaster sets for everyone you know. Just make sure your car's cup holder matches the 2.75 inch size before ordering!
