Plastic Test Tube Rack, 40 Holes，Test Tube Holder for 20 mm Test Tubes, White vial holder, Detachable test tube holder rack (1pcs，40 Holes）

This worked great for the purpose I wanted to use it for! I have a lot of hummingbirds and I use the tube feeders and have to fill them every 2 hours during summer months and was nice to keep extra filled tubes in fridge already to go in the test tube rack

No assembly instructions included; but easy to assemble

Basic test tube rack for test tubes I'll be using for storing small amounts of bulk spices. This will help me organize the small plastic bags of spices I've got in a large jar at the moment. The rack is made of thick plastic, dishwasher safe (at least in the top rack) and holds plenty of tubes so far! I'm happiy with my purchase.

I bought this for organization of larger-sized bead tubes that wouldn't fit in the normal holders. It was easy to put together and meets my needs perfectly.

Used with florist tubes to hold milkweed for Monarch caterpillars. Works great.

Well, it took 3 months to show up, so I ended up getting one locally. However, when it did show up it is essentially a flar plastic sheet that folds together as a plastic rack that snaps to together (2 pieces.) it goes together easy enough and besically does work. Even though it has drain holes in there bottom of the unit, I ended up gluing several metal strips to the base to prefent tipping over (it's that light weight.) (watch your reagents & metal contact of coures.) Cheap and simple and does the job, but the wait killed it for me. If you don't mind waiting it will certainly do the trick.

This is PERFECT for my Scentbird viles!!! Love it!! Will be buying more.

Easy to put together and work well so far

Just as expected

Perfect for our application

A lot sturdier than I thought!
