That they do what I want/need
These are really nice. Smaller then I realized, but still excellent. Surely you can find a use for these. I normally get 45 ml. These are 30ml. So unless your really low on $$$$$$,and don't want to test or play with unusual size that these mostly come in, 45ml., Go for it. 11-14-24

Cork is flaking
The cork is unstable. It is breaking apart before I can even use it.

I use these for spices!
I have a weird kitchen with lots of windows so I have only one upper cabinet. Since that one is dedicated to dishes and glasses, I need to put my spices somewhere else. I don't want them out (mostly because I don't want to have to clean/dust 30 jars!) so they need to go in a drawer. I have a narrow, deeper drawer by my stove, but most jars spices come in, are shorter and fatter, so they don't fit well, I end up with ones lying on their side on top of others and many don't label the tops so I write on them with sharpie and it was a big mess.I decided I was sick of pawing through and got these! They are glass so no weird chemicals and they fit beautifully in my drawer utilizing the height of the space, not just the width. It's very easy to pour into a measuring spoon (which mostly don't fit in the regular jars anyway.) I printed some 1-inch circle labels which I already had, but they do sell premade ones here on Amazon. I really love that everything is visible, easy to get and so much more organized now! I'm sure you could use the same system for any small things like beads or necklaces or whatever. I did also get some little plastic drawer dividers that you can customize to a grid so nothing tips over. If you have enough tube to fill your space, they hold each other up, but I didn't.
