A box for storing webbing and ribbons

It is better to keep it in a closed space; blow off the dust with a hairdryer.
It is possible to wipe with a damp cloth with detergents, you can use liquid dishwashing detergents. Drop a drop on a damp cloth and wipe the soiled places. Do not rub too much, otherwise you can wash off the color from the fabric. Then, with a clean, damp cloth, walk again, removing the remnants of detergent. It is also better to use the same clean, damp cloth to walk all over the box, so that the boundaries between wet and dry cloth on the product itself are not visible.. And you can wash it quickly under the tap, but without fanaticism and it's better to dry it with a hairdryer.
