“I saw a good amount of reviews about having to air it out because the scent is so strong; I never had that issue. While some of scents aren’t for me (I like a specific scent profile), this is perfect since it lets you try out so many different ones. And yes, they are sample sizes, but you really don’t need a lot of the oil because they are concentrated. Now I know which ones I like and what to buy!! Thank you! :)”
