Bierfilzl Merino Wollen Vierkante Onderzetter Solid 4 Pack

These coasters are surprisingly thick and have a nice, tight felt texture that catches every drop of condensation without letting it soak through to the table. I've had them for a week now and they don't slide around at all, which is a huge plus.

The merino wool soaks up condensation instantly and never leaves a water ring on my oak table. They’re soft to the touch but lie perfectly flat—no curling edges.

I’ve been using these wool coasters for a few weeks now, and they really absorb condensation without leaving any rings on my wooden table. The natural merino wool feels surprisingly soft to the touch, yet they stay put nicely under a glass.
