Several notes here to be considered.........
Kodak sold small packages of all of its chemistry in pouches in the 80s and 90s. Entire kits were sold in small boxes about 5x7x1 inch to make 1L of process chemistry. This included all color and B&W products. I still have a few boxes here with incomplete ingredients. They were not very cost effective for the average individual. The same is true of the tablet chemistry.
So, to me, everything here has been deja vu!
