12-Pack of 3 inches, 30 mL, Clear Glass Bottles Storage Container Sample Cosmetic Herb Spice Specimen Vials with Black Phenolic Screw on Caps

These were perfect I use them to put 3m adhesive primer in for my coworkers to use without chancing them spilling my big container. They sill well as long as you make sure the gasket is pressed down in the lid. I would like to know what the yellow thing that came in . I would like to know what the yellow thing is that came in the box with it.

My wife is undergoing daily radiation treatments for cancer of the larynx, and was advised to take 4 teaspoons of honey (20 ml) exactly 15 minutes before and 15 minutes after each treatment, in order to reduce the throat irritation that's an inevitable side effect. But we live more than 15 minutes away from the hospital. So, how to transport the honey in the right quantity, without spilling it or having to measure it out at the hospital? These 30 ml bottles are perfect for that. They hold more than needed so we can put a little extra honey in them and she can just drink it down and not worry about having to spoon it, or if some of it sticks to the container. They're good clear glass with tight-fitting but easy to remove screw caps, easy to clean and use.

I don’t know about the heat resistant. My son hates taking his meds by pill form. These worked perfectly when he went on a trip for special needs adults. I poured the right amount for each day in the vial. He was able to drink it each day. Thank you Amazon

It's perfect handles heat and doesn't leak !! Very nice quality !!

Love these because they ARE glass, I have them neatly and tightly lined up in a flat pouch, with spices in them for travel - works awesome. Don’t know if they are leak proof - sorry

Bought these to give out samples of my homemade hot sauces. Perfect size.

Got these to send a few cicada specimens home to my moms in Texas. They are great products and were the perfect size!

Wonderful quality, the jars are the perfect size for what I needed. Very tight seal and come packaged very safely.
