In aesthetic terms I appreciate the cardboard packaging is quality and will make the product a nice gift for the holidays. Minimalist it will not clutter your trash (significant for the environment and your patience). The candle is made of a glass (reusable later in drinking glass?) And a plastic lid I got used to sit on once the combustion saying it will prevent loss perfume or a broadcast that I did not like so.
Finally for combustion, I believe that the candle will be a life of over 25 hours.
