Pre war kaffeetüte triangular coffee bags from Eduard Leißner. When you went to the store to buy coffee, it would be put in one of these. They show some light storage wear. I don't know if I would fill them with coffee beans to use later but these would make a great display item since they have some wear already. You don't have to ruin a pristine example.
The price is for one randomly selected bag. Sorry, no choice of color. They measure about 13" at the tallest and 6 3/8" at the widest. May be rolled up for shipping.
