These work great for essential oils !  No more washing glass droppers :-)  And they're MUCH cheaper than the ones marketed for essential oils.  This product should be listed in the Health and Beauty category, too !

These are a wonderful way to mix and use essential oils.
I recently became obsessed with using essential oils for everyday use. There are so many uses for each alone or as combinations that that can be used literally everything!
I use them for everything from bug bites and beauty regimen to stain remobal and pain management.
These bottles makes the use of my concoctions so much easier and more accessible.
The bottles are easy to use and fill, as well as stay fresh and sealed very well!! They are cobalt blue which makes for longer stronger shelf life as well. The best part is now I can have the most use uses recipes on me for extremely convenient anytime use.

*I recieved these at discount for a HONEST review

We used these to add an additional seal (other than the snap ring) to 5ML bottles of essential oils. We also purchased the next larger size of these bands for 15ML bottles of oil. The larger size will shrink to fit smaller bottles too but it required more heat for shrinking. I prefer the smaller bands since I only have to run the hairdryer of them for a couple of seconds, mostly on the lid. I don't want to heat the contents.

Nice blends that work well with chicken, pork and beef.  I use them at least once a week and many times with beer can chicken

These work for my 15ml essential oils perfectly.  I expect to buy more in additional sizes for my products.

I use these for essential oils, and my husband uses them for his fountain pens and ink.  They can be used in many ways, also to give medicine to your pets and to fertilize plants.  They really come in handy.

Love these steel funnels. They are perfect if you are working with essential oils since they tend to corrode plastic and rubber.

They have semi-firm tips for blending colors and are economical . I used them to blend oil based pencils.

I love how these bottles are blue. These are the perfect size for blending my essential oils. I especially like the droppers it is so easy to use. When I have my lotions in my hand I don't need to fuss with pouring oils I can just easily use the droppers and add my blends to any of my creams. They are a bit expensive. I wish they sold them in larger bulk for a better price. I'd love to buy more.

I bought these tiny funnels to help transfer essential oils from big bottle to small dropper bottle and spray bottle, I like mixing my own oils such as Itch-be-gone, bug repellent, etc.  These work great!

I love these pendants.  I used them to DIY my own diffuser necklaces for essential oils.  They are dainty enough that they work well as they are not gaudy and they are not heavy.

I love them! They do what they are intended to do (I use them for transferring essential oils). My only issue is that they are sorta difficult to clean, if you want to reuse them. Although, not really a reason that I want to take a star away from its performance. I would purchase these again.
