Clear Glass Sample Vial, Liquid Sampling Sample Glass Bottle, 20 ml (0.67OZ) Capacity, 24-400 Thread Black Closed Top Cap,PE liner, Pack of 100

We have been using these for arts and crafts and they are perfect!They are small enough that the crafts aren't taking over the house, but big enough that everyone feels good about their finished projects.

So far these sample jars are working well for taking insect samples in the field.

This review is for: PEKYBIO Clear Glass Sample Vial, Liquid Sampling Sample Glass Bottle, 20ml(0.7OZ) Capacity, 24-400 Thread Black Closed Top Cap,PE liner, Pack of 100I am irrationally excited about these little bottles! I was so excited when they came in to see what they would be like.They come in a corrugated plastic container which is pretty cool in and of itself. It really protects the bottles quite well.Within that container, the bottles are shrink wrapped so they aren't going to be jiggling around and breaking. I like the attention to detail.The bottles are teeny and the lids screw on tightly. No leaking here.I got these for our animal rescue. We give out small vials of different medications to our foster parents. Often the amounts are very small, and these bottles will be perfect!Highly recommend these adorable, well made bottles.

As liquid vials these do the job very well. The lid has a nice seal and you can re-open and re-use without ruining it. However I did notice that when using them to store small objects like loose hardware, screws and nuts, that the walls of the glass are extremely thin. One drop off my desk onto carpet (when full of hardware) and they shatter. The glass shards are very thin and sharp. Still, they are very affordable small glass vials and are not intended for some of the use cases I've attempted, so that's more of a "me" problem.

These are very good grade glass vials that seal tightly for liquids or fine powders- to send out for lab testing or whatever. I do a lot of mineral extraction from concentrates and send out an average of samples for lab testing and the results represent potentially larger extraction methods- so the security of the sample is very important during shipping, etc. These bottles provide a clean surface inside for purity and outside for labeling that sticks securely to the glass. Very good quality vials at a good price. Great find!

I got these to hold a reference color for a water test that an NGO I volunteer for uses. The lids are nice and tight and don't leak. They're a little bigger than I needed but they will be fine for my use.

The media could not be loaded. I love these bottles on store my dip pin nibs in them, my inks in them, the one of the videos kind of dirty because it's when I was taking out camping with me, their water tight, they are glass so, I'll sometimes wrap tape or paper around it so if I drop it it don't shatter, but they're very handy. I love them.

If you mix paint for models, you need these excellent little bottles. Unfortunately, no models were provided with this paint, but as Andy Warhol once said to me, "Don't worry about the models. As soon as the word gets around that we validate parking-- well, you know."Indeed, Andy. Indeed.
