Review on Wresty 50 Pcs Clear Glass Dropper Vials 2ml Mini Essential Oils Sample Dropper Bottles - Perfect for Traveling with Essential Oils, Perfume, Cosmetic Liquid - Includes 2 Additional Droppers by Patricia Goliday

It's definitely nice but I'm not sure if I got a bad batch because I've shipped almost 2 dozen of these bottles to customers and get a lot of comments/photos of bottles only have half full. Some customers have reported that the oils continue to evaporate upon receipt despite knowing they have tightly capped the bottle as they have noticed the level in the bottle keep dropping. I also know that I sealed it tightly before shipping. This is very disappointing because many of them were filled to the brim with expensive pure (neat!) essential oil samples of things like lemon balm, frankincense, immortelle, etc. oils that I definitely cannot afford to waste. :( and yes - they were screwed all the way on! Some of the caps "got stuck" a bit when I first opened them to put in my oils. and wonder if I have a bad batch? I don't know what I'm supposed to use it to make my leftover bottles and also have a case of 3ml bottles from the same supplier but now I'm afraid to use them for fear I might throw away my oils and make my customers feel cheated.
