EISCO Heavy Duty Barnes Dropping Bottle, 30ml (1oz) - Transparent Soda Glass - 1ml Capacity Glass Dropper - Screw Cap with & Rubber Bulb Labs

I wanted something that wouldn’t break if I accidentally dropped it which I’ve already done on a tile floor and it remained intact. One thing about it you should know is that you have to push down to turn with each turn (4 in total) until it opens. At first I didn’t appreciate this feature until it fill over on its side overnight and did NOT leak. This would also be great for baby proofing. Nice job by the manufacturer.

Very thick glass. I'd estimate a 10' drop onto concrete would probably break it. Awesome product though. Would buy again if needed.

I plan on using this for scented oils. The dropper does not reach the bottom, leaves about 1/4 of inch gap.

Attractive square glass bottle, the dimensions correctly stated.Unfortunately, the provided dropper cap is the wrong size and will not tighten. The ink I use it for will evaporate and become useless. Don't try traveling with this, it will leak.Still, it is exactly the size and shape I needed because it fits my inking supplies holder. I'll look around the house for a matching cap that will tighten.Okay, I found a cap that fits. During travel, the new cap will hold the ink in, and the dropper will be put back on when working.

Works as it should
