Set of 3 different Müllers envelopes. All look identical, but each was for a different product, tooth powder, breath mints, and sachets. These are unused original envelopes with some storage wear. The back of each envelope is identical and lists the various products they offer and their uses. I find the variety of products they would package in nearly identical envelopes a bit disturbing given the products ranged from toothpowder and mints, to laxatives and moth balls it could make using anything without reading the front carefully very dangerous. I guess they didn't have an art budget for more than one design.
