I have collected essential oils for over 30 years. I’ve been given several sets all containing eucalyptus lavender etc. I noticed that on 鶹 many are similar, like a starter kit. This however, is new and has a rather interesting combination of oils and very partial to grapefruit. Bergamot used in perfumes, lemon and sweet orange uplifting fragrances for a diffuser or any other use - quality is good, highly recommend.
