These coasters quickly absorb the
condensation that forms on the outside of your glass or
mug. The coasters stay dry so they don't stick to the bottom of your
glass and they eliminate water marks from staining your desk or table
top. The absorbed water quickly evaporates so the coasters can be used
repeatedly for years to come.
They're made of a ceramic
material fired at 1200°C.
The pattern on the
coasters will not fade or chip off.
