Dangerous product
I attempted to return since I only today found that these are faulty. They have ruined several expensive blends I had made. When you screw the lid on tightly, as you should do with perishable liquids, the dropper base crushes and breaks into shards. It appears the droppers are too long for the bottle.I may go to Amazon A-Z on this one because if a seller doesn't allow returns on a DANGEROUS item, then they should not be allowed to be in business.(I'd post a picture but it seems that Amazon doesn't allow pictures - just videos.

Glass Bottle AND Glass Dropper (pipette)
Purchased directly from Amazon, and was pleased with the quality of these bottles.The bottles are glass AND the droppers (pipettes) are glass. The current photo looks confusing because the glass dropper appears cloudy; but mine were definitely glass. I also found the price (12-pack for $11.17) to be quite reasonable.The caps seem to seal well (and the dropper doesn't reach the bottom, which is a good thing -- otherwise the tip would break). Only two bottles had quality issues (some tiny bubbles in one and the bottom construction of another was off-stamped -- okay for essential oils or whatnot, but maybe not so good for other chemicals or auto-claving).btw, I emailed American Educational (the manufacturer/distributor listed in the description) to double-check about the glass droppers, and someone got back to me the next day; which I find to be super-awesome in terms of customer service.Overall, I recommend these if you're looking for amber bottles with glass droppers.

JUST what we wanted - and with glass droppers, too
I don't know how much one can write about brown glass dropper bottles, but these were perfect. We happen to use them for homeopathic and herbal remedies, and really wanted glass droppers, not plastic. The bottles are thick, dark brown (to keep out light), and the dropper is not plastic. They're exactly what we wanted.

great bottles!
great bottles! i use these to store the nicotine i use for my eliquids. i wish they would ship them in bigger boxes, as several of the nipples on the droppers were bent permanently. still usable though. but i don't know if air is getting to my solutions. time will tell. but i do recommend these as they are of good quality.

Good with careful use
The glass bottles are good, the droppers are tool long for the bottles and so push p high into the rubber stopper or get smashed in the bottom of the bottle. Just be very careful how you position the glass tubes, push them down in the rubber before you try to use them, push them up into the rubber before closing the bottle cap.

Nice little bottles
I made a quart of vanilla extract to give to various family members for the holidays, and purchased these little bottles to split up the extract into 4oz portions. I was a little nervous about receiving 12 little glass bottles in the mail unharmed, but they all arrived just fine and appear to be well made. The little dropper works great to retrieve the extract out of the bottle without spilling it all over the place, as often happens when trying to pour extract out of little bottles. In summary, these are pretty great.

Great Bottles and Droppers are a Plus!
I like to make my own herbal tinctures and essential oils, so I ordered these to store them in. It's been several months and not one has broken or been faulty in any way. The bottles came securely packaged and were exactly as pictured and hoped for. I've even packaged and shipped a couple tinctures that I made to other family members and these bottles survived the trip(s) just fine.I'll definitely be ordering more as I need them!
