Eowpower 50pcs 5ml Flat Bottom Plastic Graduated Vial Storage Container Test Tubes with Screw Caps

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.

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.

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.

These are pretty decent, but a number of them wanted to fray a bit on the edges. I also noticed when they were hanging they don’t hang perfectly straight. However, for the money I spent, I am happy with them.

Sent them back as they did not work for my purpose
