Oura Ring 4 Ceramic Polishing Pad: Keep your Oura Ring 4 Ceramic looking like new with the Ceramic Polishing Pad, redeemable once you sync your purchase in the Oura App. Due to the hardness of the zirconia ceramic, it can take on the color of softer metals, like a dumbbell or cookware. Over time, you may notice grey marks on your Oura Ring 4 Ceramic. Rest assured, it's not damaged — it's evidence of a metal transfer and easy to remove with proper cleaning. Use caution when handling metal objects and consider removing your Oura Ring for some activities. The Oura Ring 4 Ceramic Polishing Pad is your partner in keeping your ring in top condition.
