This is an eco-bag from MANN FILTER, a company that mainly manufactures tuning parts for foreign cars. They are a German manufacturer of automotive filters. This item is not for sale and is therefore not usually available, making it a rare item. It appears to be sold for around 4.5 euros on overseas websites. The size is 58cm x 48cm x 20cm. It has a gusset. It will be folded before shipping. Thank you.
