16x150mm Assorted Plastic PS Tubes and 16mm Natural Flange Caps, with Rack Karter Scientific 402S2 (Set of 60)

Great value! Exactly what I needed. Will recommend to buy.

I loved how they came quick and they came with a cool stand.

These are perfect

Easy to fill, caps were tight so nothing leaked. Cute sayings on tubes.

Made test tube "shots" to go with Halloween Mad Scientist costume/theme. The caps are very secure, so drinks could be safely handled/passed out, and everyone loved them. I made drinks that played off the colors of the tubes, different liquor for each color. Only thing is the quantity is deceiving. When poured in a glass it was less than a normal shot size. Just have to do two! LOL

Bought them for a benefit for dog rescue event. Everyone loved them and made money to Petsong rescue.

Tubes were just what I was looking for holding Scroll saw blades Caps fit well and remove well.

Exactly what I saw in pictures

I purchased the multi-color version of the test tubes to organize and store scroll saw blades. I recycled the cardboard tube rack and instead drilled some holes in a piece of scrap wood to hold them. A few were cracked at the lip, but for my purposes that's OK. The plugs fit snugly and come out with a twist. I won't be doing any science with these tubes, but they're perfect for scroll saw blades.

Product was as described. Colorful.
