I don't think these are 'pure' essential oils
Being new to essential oils, I bought this as a started set. Several of them had leak in the box they were packaged in which discolored the labels and made them hard to read. They all smell good, but I don't think they are 'pure' oils. After running a them in a diffuser each night while I slept, I noticed a sticky residue on the lampshade next to my bed. This residue has attracted dust that will not come off. I don't know if I was using too much oil and this is common, or if it is due to the quality of the oils themselves. I since purchased Now brand oils which are a little more expense, but seem to be a much better quality.
