These bottles are made of high quality tough plastic. They are colored brown to keep light from damaging the chemicals, but have a panel allowing you to write on the bottles.

These bottles are good. The tops screw on well. I just wish I had bought 1 gallon sizes b/c most of the chemicals are set up to be diluted in 1 gallon.
I use these containers to store chemicals. I like them because they come in a variety of sizes and I can always use the one that is an exact fit for the amount of chemical I am mixing.
