3 Packs Plastic Test Tube Rack, 40 Holes Lab Test Tube Rack Holder for 20mm Test Tubes, White, Detachable (40 Holes)

Rack holder and sturdy and fit the floral tubes that I purchased SEPARATELY. Easy to assemble. Great for raising monarch caterpillars and holding the milkweed branches

I bought these to hold test tubes. 3 came in one package and they were easy to assemble (folding all the sides before assembly helps speed the process up). They are the perfect size and will work with any size tubes (however I think larger tubes will work best). This is exactly what I needed! Great value for the price!

Not a “beautiful” option, but functional. Holds most lipsticks, lipglosses and lipliners. The square maybelline types being a very tight fit… but it fits. If you opt to get the larger hole 21 or 24 squares per holder that likely won’t be an issue, but I needed the 40 squares per holder size for all my lipsticks to fit. For lipgloss, lipliner and taller tubes assemble the holder as intended, for normal lipstick hight you only need the bottom rack attached. 3 can be placed side by side in a simply tidy 12 x 12 (17.1” x 15.2” x 6.1”) storage keeper.

It is a little flimsy if you pick it up by the top. Otherwise it is sturdy.

Perfect for holding cigars in my humidor. Will order more, theyre easy to put together, strong, and seem durable.

I purchased for my juice shots and it has proven to be great to work with, the design is both functional space- saving, it allowing me to organize my tubes with ease

Needed to find a means of holding 6 sample vials other than by hand. Gave these a try as an experiment and they worked wonders. Allowed for proper sample vial filling and great ease of "clean up" (rinsing) when finished. Definitively now part of our sampling procedure. I'm using on the east coast and my colleague was so impressed he took the extras for use on the west coast. Highly recommend.

I will keep the item but it's not a great fit for floral tubes. The title says test tubes and the description says floral tubes. I did not notice the descrepancy when I originally ordered. It will work for my monarch setup but isn't a great fit. It barely fits in the enclosure and the floral tubes are very loose. Also you will have to assemble these.

Llegó rápido. Facil de armar, tal como se describe.
