Here are a couple of extras that I recommend getting in your first order. Both are in the accessory section when you are ordering.
One is the essential oils bottle labels. I store all of my oils in a drawer and it is so nice to be able to see what each oil is from the top of the bottle.
The other accessory I LOVE is the AromaGlide Roller Fitments. The starter kit comes with one of these, but I use them so often. There are some oils that I don’t diffuse very often, but apply to the bottom of our feet and the roller ball makes it so much easier and reduces the risk of spilling (every drop is precious!). Since the starter kit, I have ordered more of the oils that are in the kit. For many of my oils I have a small bottle with a roller and a large with a dropper.
