UNITEA coaster 100×100mm / 4x4in

The 100×100mm size is perfect for my tall glasses, and the surface holds up well even with condensation dripping down. I like that I can still see the tea color through the glass while it sits on the coaster.

The arched design actually lets me watch the tea leaves unfurl right through the glass while the cup rests on it—such a simple pleasure during my afternoon break. It’s sturdy enough that I don’t worry about spills, and the 4x4 size fits perfectly under my favorite mug.

I was skeptical about glass coasters feeling fragile, but the arched design gives them surprising stability on my desk. Watching the tea leaves bloom through the glass while the cup sits on it is a genuinely calming little ritual now.
