The Avyn candle holder has an applied colour finish and is not solid coloured glass. To care for the item, we recommend washing with a mild dish soap and warm water to remove any excess wax after every use to prevent a build up. Please do not use harsh chemicals or abrasive cleaners as this may damage the finish. Please position the candle securely. This product will get hot in use. Keep out of reach of children. Wait until fully cooled before handling. Never leave a burning candle unattended.
