ZEJIA 3 Gram Sample Containers with Lids, 50 Count Tiny Sample Jars, 3ML Makeup Cosmetic Containers for Lip Balms, Lotion, Powder, Beauty Products(Black Lids)

Great for packaging small items. They are definitely leak proof, and the benefit of plastic is that if you drop it, it doesn’t break. Very sturdy.

Small enough to give a sample and not waste product

These were perfect for my lotion samples

I'd you're in need of fifty quarter-sized vessels with a nickel-sized interior able to hold about three and a half grams of...product...then these are a solid choice. They don't let the 'powder' get in all the grooves and threads for the cap. It's just a solid way to store about a 'balls' worth of...whatever it is you desire. It's a great option for those in the US who work in one of the only industries that use the metric system. Get yours, today!

I bought these to hold small amounts of solder flux, a volatile liquid that leaves behind a thick residue which is impractical to clean. Assuming the plastic withstands the flux they seem ideal, considering the size, the lid (to inhibit evaporation), and price.

I am using them to store parts used to repair glasses. On a recent trip I had a screw fall out of glasses and I could not find it. When I returned home, I bought an eyeglass repair kit and used these containers to separate the different sizes, etc., as they came in a box with a snap lid that would scatter parts when opened. I put a combination of sizes into a couple of these containers along with the magnetized screwdrivers into a pencil bag to go into my kit that travels with me.

I'm running a small business and these little jars are perfect for on th spot samples for my guests! Spill proof and even smell proof!

Used it for skincare samples…perfect size as my product goes a long way.
