Review on 🧪 Yesker Amber Glass Bottles with Glass Eye Dropper 30 ml (1oz) - Pack of 6 for Essential Oils, Chemistry Lab Chemicals, Colognes & Perfumes by Miranda Jones

I actually bought another set of these glass bottles from another store at the same time as these (the other bottles were 2 oz). I thought they were really nice when they came out, but once I started using them, there were some issues. For some reason the drippers were a little tricky to put together, although I've collected quite a few in the past. I bought them to fill with road fluid and they worked fine for a few days. However, after three days, some of the rubber caps on the bottles had swollen and never returned to their original shape. It was very strange and because they were swollen the drip stopped working. I'm not sure why this happened, but I suspect it could be due to some kind of reaction between the liquid I poured and the rubber. The ones that were puffy had Thayer's Witch Hazel Face Toner, which is alcohol-free and doesn't contain any other chemicals to my knowledge. I'm not sure why this happened. Revain's customer service was fantastic and I was able to switch bottles but I would be careful what you put in the bottles especially if it gets on your skin!
