I was one of the lucky ones. I only succumbed to the Frog a little while before finding this place so my CYA never got "off the scale" but, I store the large bottle of R-0013 in the lunch box because I only use it about 3 or 4 times a year and I also store the borate strips and salt test in the lunch box along with a bunch of other stuff (liner scrap, extra vials, another stirrer, extra stir bars, etc).
The folded paper towel is dual purpose. It provides a cushion making it easier to remove the scoop and it keeps the compartment clear of any powder granules that may be left on the scoop.
I have thought about repurposing an R-0871 bottle and filling it with R-0013 CYA reagent, but I haven't done it yet.
