The Resink coasters are made with resin that is left over after coating earrings. These are a way for me to reduce waste by creating a usable product with resin that has no purpose. You can use these coasters to protect surfaces from water rings or use them as a trinket tray. 
This coaster is made of 2-part epoxy resin, alcohol ink, and cork.
