I absolutely love them when I'm making my own formulations. They work really well and stand up to a lot of use.
I use these all the time for my bug repellent spray and hand sanitizers. I love them. They fit nicely in my purse and are very durable. Not to mention they look good. I use the frosted ones.
I purchased (3) packs of (6) of the frosted 1oz bottles at the convention and every single one of them have leaked when shaking to get the oil distributed. Very disappointing as I was making these for purchase at a booth and for friends for gifts.
I have the 1/2 oz bottles, they are perfect for me to take in the go! I add my essential oils and dilute with my carrier oil!
I bought 2 sets of the amber with the dropper and I added 6 of them with oils. They all evaporated within 2 months inside of my oil bag and one oil even disintegrated the dropper after the oil evaporated out of it. The day after I placed all the oils in these containers I can smell all the oils coming out, even though they we're inside a travel bag. It was obvious that they containers weren't keeping the oils in. I'm sad because a lot of my oils evaporated and they we're my first order of oils and I lost most of them.
We do see that you left a review on the 1 oz amber bottle with droppers, which is different from the 1 dram you purchased however, because evaporation is somewhat common with this type of lid we would suggest make sure to dilute any oil that is going to be in a dropper so less oil is 'lost' and only add a dropper when you know you will be using that oil frequently, or for thicker oils that do not tend to make drops as easily.
