API Replacement Test Tubes for Aquarium Test Kits 6 Pack Bundle

I had ordered these to replace some test tubes and to have back ups, but upon arrival two of the test tubes were completely shattered, unusable. Another two were chipped and just this morning one of those shattered while placing the cap on. Im not going to use the second chipped one because its just to end up completely breaking. TL;DR I ordered 6 test tubes, and I received 2. Manufacturer packaging was intact and bubble wrapped, no apparent damage to the box it was delivered in.

Its great just like original that comes in test kits.it did not give me total test tubes that were supposed to be in package

The caps are kind of big so the water spills during shaking

Good replacement tubes. Unfortunately the test tubes are easy to break. Fortunately, you can buy replacements!

These are the exact replacement for the API test tubes. Just wish they were a little bit thicker glass.

Delivered as shown and described

great. just like original

They are very fragile. Thickening the glass would be a nice touch even if it made them a bit more expensive.

Horrible, breaks easy.

In my opinion, these are easier to open then the ones that came with the Api Freshwater Kit and its a good thing I bought these because slowing that came in the kit are breaking. But these are worth the money.
