Eowpower 50 Pieces 5 ml Flat Bottom Plastic Graduated Sample Vial Storage Container Bottle Tubes with Screw Caps

I only needed a few for my sewing machine needles, but will come in handy for other uses as well. Pills, small buttons, etc. I haven't used for liquids but I think they would be okay since top screws on. I also added a small piece of wooly yarn to protect the needle tips which was suggested by another review. It stops them from moving around. I labeled the orange top with a marker or you can stick a label on them. Overall, they serve the purpose that I was looking for.

never used them but they did come fully equipped.

I got these to hold fountain pen ink samples. The tops screw on very securely. I always wrap tape around the top just in case when I'm sending samples by post, but I've never had an issue with leaking yet.

Not sure if I didnt screw tight but some leaked oil Not bad product tho

Perfect for storing small pieces

I bought these to take premeasured black powder charges out with me to the range or hunting.. I'm actually using these with Triple 7, and if you're careful, you can get 110 gr by volume in them. Work great, no leaks, 50 will probably outlive me !

These are clear plastic non breakable screw cap containers for your gold dust, flakes, pickers and small nuggets. I got these to replace the glass ones I have, I don't trust glass in the field.

I kept breaking the glass tubes that came with my fish water testing kits. This is a much better replacement and doesn't leak so you don't have to worry about getting the chemicals on your fingers.

Well made with a o ring seal.

Exactly what I needed
