Our mom taught us to always use a coaster. That lesson stuck--so much, in fact, that we think EVERYONE ought to use coasters, so we are offering these artisitic ones from Lantern Press. These are cork-backed and super-absorbent, measuring 4" x 4" x 1/4".  Use just a single one, or pick out several different varieites for a mix and match set. Seven (count 'em, SEVEN!) options available.
