Ackers Science 250Pcs 2.0ml Polypropylene Graduated Microcentrifuge Tubes with Snap Cap,Natural

Great for blackpowder

These are awesome little leak-free liquid storage holders. I use them for adding essential oils to the simmer pouches I create. They are also great for flavor enhancing—like adding a few drops of syrup or extract to something you're gifting. These are awesome and you get a lot inexpensively.

Perfect for storing that last bit of spice or medication. Seals well.

Good product for fair price.

The package came in neat and was in a ziplock. The reason it was 4 not 5 star review is because some of the items were broken upon arrival

There is nothing to dislike! They are perfect for storing seeds, highly recommended!

It definitely got the job done…thank you

I like the product but the delivery driver posted that they left it in our at the mailbox and there is a lot of package theft here and I never received it. The delivery instructions say for them to deliver to the apartment door.

Los tubos no son de la calidad de axygen, pero se pueden utilizar para protocolos dónde no se necesite incubar a -20 °C

Más del ochenta por ciento de las tapas están a la mitad, los tubos están defectuosos.
