Review on 🏺 Vivaplex Amber Glass Bottles: Convenient Travel Accessories for all Your Needs by Doris Tran

I use them to make custom essential oil blends for other purposes. My only complaint is that the plastic corks that fit into the cap (to prevent them from leaking I guess?) tend to get caught on the neck of the bottle when unscrewing the cap, meaning you have to pry them off and push them back into the cap (and in my case oil got on my fingers). I haven't tried storing them anywhere other than vertically on a shelf, so I don't know how airtight they are.
