Michigan Smiley East Coasters 10” diameter. Made in the U.S.A. from Recycled Materials. Part of our “Coasters For A Cause” campaign, proceeds from the sale of this dab mat are donated to Michigan Glass Project who in just a few years has raised and donated around a half a million dollars to help put art programs back into the school curriculum in the Detroit area. One of our favorite causes : ) Check them out at www.themichiganglassproject.com
