Jump start spooky season with fun Halloween themed coasters! Set of 4-one each spider, web "Boo!" and "Eek!" Black background with a subtle hint of iridescence. These coasters stack neatly and have cork attached to the bottoms for additional protection for your furniture. Handmade in a multi-step process. Sizable, 4 inch diameter. Food safe and heat resistant to 500 degrees. Care: Wipe as needed with a damp cloth and dry with a soft cloth. As a resin artist, I recognize that this is not the most eco-friendly medium. To balance this, I do my best to minimize waste during production, use recycled or compostable shipping materials when possible and even recycle some of the shipping materials I receive in products I order to pack some of my shipments, while still keeping the packaging and unboxing a pleasant experience. I hope you see this as a positive process of environmental responsibility.
