- Twdrer 50PCS 5ml Plastic Graduated Vial Tube with Screw Caps,Small Test Sample Bottles Tubes Container with Lid

Holds liquid and the lids screw on easily enough. Being made of decent plastic they are holding up well.

These 5ml Twdrer mixing vials are perfect for glow and pigment powders. Seal tight, keep moisture out, and just the right size for adding small amounts into rings. Durable, convenient, and I’ll definitely buy again once I somehow use all 50! 😂

These containers are perfect for storing my very most precious rhododendron seeds in the refrigerator. The caps are great, too, as they are secure and protect the items inside. One problem with glass or plastic small containers with seeds, however, is that static will retard the seeds from easily being poured from the container unless it is counteracted with a radioactive wiper made for the purpose or a discharger.

Muy buenos y útiles , la tapa es un poco deficiente

The work well for my application.

Good quality vials. I use them for needles that I ship to customers.

These work great for holding ink, so far no leaks whatsoever.

I’m sure you can use these for many things, but I have used them for fountain pen inks when I share them with others who want to try a small quantity of an ink without buying a whole bottle. They are just the right size and cap tightly, and definitely seem to be quite durable.
