I was expecting the original glass ones but received plastic tubes. They look fake. They work but it’s not what I expected.

Exactly the same quality as the test tubes in the API water testing kit. Great quality, would buy again.

I broke mine and needed to test my aquarium water after adding a new fish. These came very quick and at a good price!

Received all 3 in bubble wrap, none were damaged. I broke the first one I got with the kit, and scrambled to buy more I didn't expect them to all come in prefect condition. but they did I am very happy and will purchase this again.

Products better than expected. The bottles I received actually have the 5ml measurement line, which can not be seen on the picture.
