Measuring Cylinder Set, 4 Sizes Graduated Polypropylene Lab Test Tubes in 100 ml, 50 ml, 25 ml, 10 ml for Laboratory, & Science Experiments with 4 Plastic Droppers in 3 ml

I got these to measure additives that I use in my aquariums. I did not have anything accurate to use for the small quantities required. These work well and they are easy to clean

I like these but be gentle washing the writing on outside because it fades

I immediately put these measuring tools to use I am very happy with the quality and the readability and the accuracy and the actual performance of the instruments.

Works for measuring fluid volumes accurately compared to certified standard measuring device .

Sturdy well made product

100 ml arrived broken. I have a 100 already. I needed the smaller ones so not bothering to return. Still sucks.

I ordered this for my son's science fair project. very happy with this product made the project alot more understandable for my 9-year-old.

They work for what I needed them to work for
