Sertodo Copper Napa Coasters

Yes, as pure copper, these coasters will naturally develop a rich, darkened patina with use and exposure to air. If you prefer the original bright finish, you can easily restore it using a standard copper polish.

While the copper is durable, it is a metal surface. We recommend ensuring the underside remains clean and dry to prevent any potential scratching or moisture rings on delicate wood finishes.

Simply wipe them down with a soft, damp cloth after use. Avoid using abrasive scrubbers, which can scratch the hand-hammered texture, and ensure they are dried thoroughly to prevent water spots.

With a 4.5-inch diameter or width, these coasters are generously sized to accommodate most standard glassware, coffee mugs, and wine glasses comfortably.

These coasters are crafted from solid, heavy-gauge copper without an added synthetic backing. Their weight helps them stay in place, though they do not feature rubberized grips.
