Felt is a flexible material therefore the slippers will soon adapt to the shape of your feet. After wearing them for a few days they will just slip cosily on to your feet.
Slippers are made of 100% wool felt.
When they get dusty remove the dust with a vacuum cleaner or adhesive tape.
Never brush slippers because the fabric might pill or even tear.
The slippers can be washed in the washing machine at 30°C – wool programme (!) using a very gentle soap for wool. Before washing, remove any dust with a vacuum cleaner. Because wool might shrink a little, after washing put the wet slippers on your feet so that they once again adapt to the shape of your feet. Then take them off and let them dry. To keep the shape you can also stuff a soft plastic bag into them. After they have been washed the slippers might get a bit smaller.
If you wash the slippers by hand DO NOT use a brush on any art of the slipper!
If the outer edges start pilling, cut the pills with scissors.
