Five wooden coasters with thickened felt built into the face, which is what actually stops a ring forming: the felt takes up condensation as it runs down the glass instead of letting it pool on the wood.
Absorbent face. The felt insert soaks up spills and adds heat insulation under a hot mug.
Non-slip base. Four soft pads on the underside protect the table from scratches and keep the coaster from sliding.
Generous size. Large enough for wide-bottomed glasses and tall cups, not only for espresso.
Sturdy. Flat, stable and hard to break, so a dropped coaster is not a ruined one.
Set: five, in black.
The felt releases the glass cleanly rather than lifting with it, which spares the noise and the near-miss of a coaster falling off mid-sip. Works with cold and hot drinks on a coffee table, a dining table, a bar or a desk.
