Want an unbreakable coaster that actually absorbs the beads of humidity before they roll from glass to coaster to table? This coaster saves your table, and there is nothing breakable here. No worries about the accidental drops to the floor we've all experienced. These 100% cotton coasters are absorbent and dishwasher safe. Just lay them flat on a dishtowel after the washer stops. The coasters come as a set of four and measure 4 inches across. They are tied with the same knot as our famous sailor knot bracelets, just turned flat. Use with mugs, glasses, cold bottles of beer and even candles. At first glance, you'd wonder how your glass will balance, but as soon as you try them, you realize that the five upper most facets are all level and your drink balances as well as on any other coaster. absorbent, unbreakable, washable, handmade here in America for over 60 years and ready for you..
