> 3 dayBecause, you know, you might have broken a few. Much better deal to get the pack than a 3 or a 6.

> 3 dayAll the tubes came in perfect condition. No broken tubes and even the box is in perfect shape. The tubes themselves are just as they should be. They have lines marking 5mL and caps. A wonderful purchase to make water testing my tanks easier.

> 3 dayMy clumsy self cant seem to stop dropping these darn things, so being able to buy 24 replacements is a blessing. These test tubes have given me new motivation to track the water quality in my three tanks. Straight-up magic, I swear.

> 3 dayAccurate to 5ml line. Tops are just a bit leaky like mentioned. Most irritating to me was I only received 22 of the 24.

> 3 dayI love these. Ive broken so many by dropping them on a tile floor and decided to buy this instead of more test kits and it was absolutely worth it. You should pick up the test tube rack as well because that makes doing water tests all that easier. You can also test your pool with it too if you want. I do just because I can. Two different tests are better than one right?

> 3 dayI needed these SO BAD (and will probably need more again soon). The glass tubes just break so easily, and its REALLY HARD to find more! I got this larger box, and everyone around me wanted to buy just a few off of me! We ALL needed them!
