Bins are shipped folded, so creases are inevitable. Please steam (iron) with middle heat to smooth out the creases. I usually put a piece of cloth between the felt and iron when I steam. It takes time but it works well.
Wool felt will pill on its surface after many years of use. Use a safety razor or a pill remover to carefully remove the pills and the product will be as good as new.
It’s impossible to wash the whole felt bag, but you can partially clean it. Spot clean the stain by applying detergent to a separate cloth and dabbing it.
Although a few percent shrinkage occurs, you can wash the insoles. Take off the insoles and wash gently by hand in warm water under 30°C. Dry them and steam iron with middle heat.
