Always protect the inside of the base with 1 cm of pebbles, sand or rock salt. Please follow our recommendations on the size of the tealight/candle to use depending on the size of your Lantern (never exceed). Make sure the tealight/candle is well centered with the wick up-right in your Lantern. We recommend that you DO NOT use a scented tealight/candle inside your Lantern as the flame is always larger and could damage your Lantern. Never place in direct sunlight or near heaters. Once lit never leave unattended.
