Store your bag in its dust bag, keep it away from moisture and direct sunlight, and clean it gently with a soft dry cloth. Avoid harsh chemicals and excessive friction.
I ordered a product with discounts, this is not my first bag but this one didn't arrive. I communicated with the seller for a very long time and it was tedious, but they always responded promptly. The package got lost somewhere in the Netherlands, no one could find it. We searched together for a very long time and eventually got a refund. The bags are of excellent quality.
