ABSTRACT:
The present invention provides a coaster for a drink container characterized in that the coaster incorporates a microporous structure capable of absorbing liquids which fall upon the surface thereof. Such a coaster, provided it is of appropriate dimensions and porosity, can prevent any spillage or condensation from reaching the table surface, yet will remain externally dry.
