I had a small set of essential oils that I used many of but noticed there were several I wanted & didn't have. It didn't make sense to buy those scents indivually, as they're expensive one at a time, and I knew I'd use some of the scents far more than others. I enjoy making candles so I use some of them in that way & use some by adding the scents to coconut oil & creating both roll-ons & sprays, and finally, I add some of the scents to my bath water, specifically the eucatlyptus if I'm sick particularly with a cold, lavendar for nearing bed time, & other lovely scents simply for beginning my day, although I rarely bathe before heading out usually taking a shower. I don't use a diffuser but if I want a scent in my atmosphere, I simply add a few drops to my candle watmer rather than using a candle, at times. This is a particularly good set, especially for the price, & I wholeheartedly recommend it, particularly if, like me, you find several uses for the essential oils in your home.
