Coasters are quite versatile, a little life's fact we never knew while we were in CA. Since moving to the great state of Texas, we've been having friends and family over on an almost weekly basis, and soon found ourselves needing light and good quality coasters.
Our 3.7" diameter coaster is in heavy cardboard and 0.062 thick, it has our Cygnus logo on top. Being our logo has an OD green background, these duck coasters are mostly covered with ODG waterproof ink, a nice feature for a coaster, we've seen condensation ruin cardboard based coasters.
Given their low cost, free shipping isn't offered, they're best bought alongside their companion whisky glasses.
