Blue Onyx Marble Coasters with Cork Bottom, Gold Inlay (Large Size | Set of 4)

These are beautiful and work well. I love the porosity of the stone so condensation doesn’t pool up. They are very sturdy and high quality, but I can see young children breaking them over time. Definitely something to get out when adults are around, and give the kids some basic ones that won’t scratch your furniture or break if they throw them around.
