In order for years to clean at last, I have washed it in Hand wash with warm water and mild detergent.
That it has left this a little color, has not bother me as the fact that it is largely fallen outside of the form, it is now almost square:
in height by 3-4 cm high (!) shrunk,
the top edge has contracted by one centimeter,
for the bottom edge is one centimeter become broader.
Now stand 18/19 cm high paperbacks almost from the Sackerl out, slightly larger books are over, the corners meet from now. The Sackerl has now only a utility for Reclam booklet.
I find that quite disappointing for a small colorful cotton Ackerl by almost 9 euros.
ps: the dimensions were in front 20 x 25 cm (just like in the Amazon Short description given, the product information listed below continue to be incorrect)
