Honbay 30PCS 2ml Plastic Empty Dropper Bottles Portable Eye Drops Containers with Screw Cap and Plug

They are small like I wanted and great for travel. The caps come with a seal on them so when you put them on they seal in place and you have to break the seal to open.

I carry a saturated saline solution with me when traveling, and I add a drop of it to every glass of water. Makes the water feel less harsh, so it doesn't give me a headache. At home, I do the same thing, but with a medicine dropper bottle. These little plastic bottles are perfect for traveling.

Despite other reviews, I received 30 each of all the pieces. The volume is around 3ml, not 2, which was fine with me. The safety seals, or whatever they're called, don't work well, but I didn't need them and they're easily removed. Without the dropper insert, they can leak when squeezed, but with the insert, they seem fine. The cap is a very loose fit on the bottle, so it's easy to "strip" the threads, meaning you can get them only so tight before the threads skip. My application is to hold small quantities of mixed paints for airbrush use, and they should be great for that. The only downside is the polyethylene bottle won't take Sharpie ink very well, so you need a label.

The media could not be loaded. They quality is pretty good is just that it’s definitely not 2mL for sure, when I measured, they are about 4ml at least.It’s fine for me because I am just using them to keep my cuticle oil on my desk so I don’t have to keep a 2oz bottle that can potentially spill.

Small, compact, and leak proof. I use the containers to fill with eye drops and they work well for this purpose. Easy to assemble and affordable. Not much else to say.
