Bierfilzl Merino Wollen Ronde Onderzetter Multi 6-Pack

The natural merino wool is thick enough that condensation from my iced coffee never seeps through to the wood table. Each coaster in the six-pack has kept its shape perfectly after weeks of daily use.

I was worried these coasters would be too thin, but they're surprisingly dense and absorbent. They've already saved my wood table from several condensation rings.

These coasters are nice and dense, so they don't slide around on the table. They’ve soaked up a few cold drink drips without leaving any rings on my wood surface.
