Review on 🔵 Cobalt Blue Glass Bottles Droppers for Lab & Scientific Use: Quality and Durability Guaranteed by Louis Asok

I bought these droppers to dispense a large amount of cuticle oil. It took me some time to find the right ones and let me give you the criteria I found: 1. Glass that is actually blue as opposed to just blue tinted glass. Yes, I've found many just painted a flaky blue. It is actually blue glass.2. dropper length. MANY of the ones I first considered had drops that barely made it halfway through. Garbage! You have a dropper that goes all the way down and you can twist it to get the last drop.3. tightness. Many are clearly leaking, but these are not at all. Did a lot of tests. filled the eyedropper, squeezed and pulled on it, also sideways, but upside down. no leaks in any of the 8 I've filled in so far.4. Are regular sealed lids included? These are not. You only have drops. Some also come with a set of regular caps, but they were more expensive, so I went with these. I mainly work with carrier oils so you can always leave the pipette cap in place. With hard (true) essential oils, a rubber dropper may not interact well with the oils. It just depends. But I'm happy with that for myself. The savings were definitely worth it. You look amazing and impressive! My oil is a little golden yellow so it gives a green tint to the light. It looked pretty cool and I was happy to give it to the few people I gave it to. (By the way, my cuticle oil recipe is a generous amount of silky jojoba oil, a little grapeseed oil, a little sweet almond oil, a little avocado oil, and a little lemon essential oil for scent and shine.)
