Four stone coasters featuring vintage bike illustrations is the perfect gift for the bike enthusiast.Each coaster measures approx 4x4 inches and is made using tumbled marble tiles. The vintage images have been applied using a transparent technique that allows the natural color and character of the stone to be featured in the design. The set has been well sealed to ensure years of use and durability. The back of the coasters are fully backed in cork to protect surfaces.In making this line of stone drink coasters, I was hoping to create a collection that was very stylish, eye catching and, above all else, useful. These coasters are a perfect way to incorporate some of your personality into your decor. The best home decor pieces are ones that really reflect you... your tastes and interests. I hope that you find something in the collection that "speaks" to you.The coasters are great for both hot and cold drinks but are not to be used as a trivet for hot pots or pans. They are not dishwasher safe. Please wipe with a damp cloth, when needed.Please leave 7-10 days for production of this set.
