Photographers' Formulary 10-0030 100G reviews

Potassium Alum - 100 Grams is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from It was great! The potassium alum was pure and was in a very, very fine powder. Just what i wanted. The only thing is that the bottle was misleading in its size. (Almost 2x as big as there was as alum.)
