I am glad these are packaged in a container; we have had some in the past packaged in a paper envelope (from another company), which is hard to keep dry. They work just as advertised - the only imperfection for us is that the colors are fairly similar and it can be hard to tell at a glance what the result is. Otherwise, great.

-Great product, arrived quickly.
These Chlorine test strips are great when you need to measure Free Chlorine levels in water at high levels of concentration.
