PEKYBIO 20 PCS 4 ML (1 dram) Clear Small Liquid Sample Glass Vials with Screw Caps, 15 mm Diameter x 45 mm Length Leak-Proof Vial, 13-425 Black Screw Cap with PE Liners

These are so great and I’m really glad I got them! The screw down tops make it easy to seal whatever I need to put in them (I use mine for essential oil blends) the size is exactly what I need and they are small enough to keep in your pocket or purse and use throughout the day. I really think this is such a convenient little bottle and easy to open and close. I haven’t had any issues with leakage and the cap says closed so I don’t have to worry about them spilling in my purse. A+++ little bottles LOL!

I recently had to deliver a fecal sample from my cat’s litter box to the vet for parasite detection. They are the perfect size for samples. Not too small and not too big. They are also sturdy enough for that. A small sample an inch long and a 1/4 inch in diameter will fit nicely in here. I’m not sure but it is probably too small for a urine sample.

I'm not prone to writing good reviews for anything I purchase on Amazon simply because 9 times out of 10, the products just don't measure up to what they should be. Seems a lot of companies send their seconds or defective products to Amazon to sell, but nevermind that right now... These little bottles are exactly what I needed for how we take our vitamins (as powders from VitaSpace), and if you're careful, they hold up well. Oddly, once I got all the broken glass from the one crushed bottle out of the container and washed all the remaining 99 bottles, only 91 of them fit back in the container! I cannot figure out how they originally got 9 more in the package/container it came in - even my very clever hubby can't do it! Odd, but it affects nothing - these are really great little vials that can have so many uses!

I buy these a lot. For work, science. I also buy a box for my 3 year old. She collects sand in hers! Good size, functionality, no leakage ever, and a three year old hasn't broken one yet, so I'd say excellent durability.

Great containers I wish they had marks on them though for the amount that was going in them

We purchased these so that we could put them into a cocktail bouquet, taped to a short stick. We filled them with aromatic bitters, so that the recipients could make an old-fashioned cocktail.

These came in super handy for that, but now I have 15 additional bottles to find a use for.

Just like it was described. The seal is nice and tight and the glass is thick enough to make them safe and durable. I will definitely be buying more of these when I need them because the price is great!

Durable easy to fill.
