Using these Ferm Living Double Dito Stoneware Candleholders is easy. Simply place a candle with a 22mm diameter inside each holder. You can put them on your windowsill to catch the light or on the dinner table for a cozy atmosphere. When it comes to maintenance, use a soft, dry cloth to gently wipe the holders clean. Avoid using harsh chemicals as they might damage the reactive glaze. If you want to return the item, don't worry! It's covered under our 30 - day return policy.
