We decided not to do advent calendars,but instead, we have introduced our 8 segment clamshells that have 8 different beautiful fragrances. 
There is a choice of Christmas, Designer Inspired or Malone-esque. They are all handmade with 100% eco soy wax using high quality fragrance oil. Eco soy wax contains no paraffin and is made from soya bean oil.You use these mini melts in your oil burners by simply placing in the dry burner and lighting an unscented tea light below. Please ensure your burner is dry and do not add any other substances like water to the wax. The fragrance is released when the wax melts. The burn time depends on the quantity used and on fragrance selected and depending on the environment in which they are used.
 
AND PLEASE REMEMBER, NEVER LEAVE YOUR OIL BURNER UNATTENDED WHEN IN USE....
