ETTSNU 10PCS 4ml Clear Glass Vials with Screw Caps and PE pad, 1 Dram Small Lab Sample Vials with Lids, Leak-Proof Liquid Storage Empty Vial (with Droppers and Marker Stickers)

These work great for my essential oils and individual doses of tincture. The clear stopper on the bottle under the black screw on top are just what was needed to keep leakage from being an issue.

These are great little vials. They're made well and do not leak.

I used these in a science class. Ground analgesics dissolved in solute. I did not need to fill up the bottles - they held a larger volume than I needed. There is a plastic insert that goes into the bottle before you put the lid on. I suspect without this piece, the liquids would leak. But I use this piece, and I had no trouble with leaks. The glass feels very thick. I was not worried at all about accidental breakage.

As advertised. Pipettes seem good quality and better than a different bulk order I purchased. Vials are quite small, so ensure you understand what a 4ML vial means

Good quality, just a little bigger than I thought. 20 ml would probably be the right size for me.

I wanted something small & durable to mix powdered medication in warm water to later add to a cold flavored drink (the powder doesn't dissolve well in cold liquids). These work great for me. I prepare the mix in all 10 bottles (granted, it takes a steady hand & a measuring cup with a good pour spot to hit the mark) & refrigerate. (I even use the little box they came in to store in the fridge.) Ready to go when needed & small enough to put in my pocket for travel. Bonus, they come with labels. No regrets here!

I really like these little glass vials. I can carry anointing oil and good salt around in my purse. No spilling, not too hard to open or fill or pour from.

I use these vials for muzzleloader charges perfect size very convenient
