Ready for hot and cold drinks

These silicone coasters suit anyone who wants a simple barrier between beverages and tabletops. They handle coffee mugs, wine glasses and beer bottles without slipping or sticking to the cup. Food-grade silicone keeps the set safe for daily kitchen or bar use.

Heat resistance under sustained use

The material is rated to 600°F, so a steaming mug left for an hour will not scorch the coaster or the surface beneath. Deep grooved channels trap condensation and prevent liquid from reaching the table. Airflow ripples on the top face stop the coaster from clinging to a wet glass base.

Silicone build and everyday care

Each piece measures 4.06 inches across and .25 inches thick, giving a stable footprint for stemware and heavy mugs. The high-grip underside stays put on polished wood, glass or stone. Machine-washable or dishwasher-safe, the coasters resist warping and can be rinsed clean in seconds.

Questions about this item

How much heat can the 600°F-rated silicone handle during all-day use?

The food-grade silicone resists temperatures up to 600°F, so hot mugs or pots can sit on the coasters continuously without warping or degrading.

What surface does the 4.06 in coaster need to grip properly?

The non-slip bottom pattern works on any clean, dry tabletop — wood, glass, stone or laminate — without additional pads or adhesives.

Will the .25 in thick coasters sit flat beside older, thinner cork mats?

At .25 in thick they sit slightly higher than most cork mats, but the flexible silicone edges keep the transition even so cups won't wobble.
