Some Burners may have some small imperfections.

Always use within sight, and never leave unattended
Always ensure that you do not overfill your bowl
Keep melted wax away from pets and children
Do not eat
Never pour melted wax down plug holes
Wax / burner will remain hot after the tea light has been extinguished / burner switched off
Do not try to move the burner until it has cooled completely and the wax has hardened
Do not add water or fragrance oils to wax melt well
Keep wax clear of debris
Only ever use unscented tea lights as fragrance ones burn too hot
Only use standard sized 4hr tea lights. Never use the larger 8hr tea lights or multiples as these can cause the burners to break
Never place burner in freezer to help dislodge wax. This can weaken structure of the burner
Ensure that the surface under the burner is heatproof
