I have a bunch of small perfume samples and needed a better way to store them as they tend to topple over and roll off the counter. These are sized perfectly.

These are decent test tube racks for the price. If you don’t need very many they’re a great value as they are sold for significantly more when dealing with laboratory supply companies (provided you aren’t buy massive amounts of products from them and getting bulk discounts). They can be a little stiff when assembling and wrangling all the tabs into said slots.

I normally prefer wire test tube racks and have looked at these plastic racks several times but have been pretty dubious about quality. Wire racks in some sizes are getting hard to find in 2022 and have climbed in price, so I decided to give these a try. While they are a bit on the flimsy side, they are a pretty good value. They hold together securely, although the plastic is sometimes a bit out of true. They fit 25mm culture tubes very nicely and have just enough spacing between cells to allow for a good fit even with caps that are widely belled.

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.

These are ok but the info said that the holes were bigger than what they actually were. They ended up too small for my needs. They are not a bad rack just need to put the correct size of the holes.

I use these racks with the RESTCLOUD 16"x16"x24"h butterfly habitat, where one rack fits perfectly, and holds the DEPEPE 50ml Clear Flat Plastic Test Tubes filled with milkweed cuttings. The racks are sturdy and lightweight, and THREE is the right quantity when it comes to cleaning the enclosure...rack #1 in the habitat with the cuttings and caterpillars, rack #2 holding clean test tubes with fresh water, and rack #3 ready to receive the dirty test tubes.The racks are easy to clean with bleach spray, although sometimes a toothpick is required to poke frass from the rack.These racks, along with the aforementioned test tubes and butterfly enclosure, make raising butterflies easy. I highly recommend.
