The bag I found beautiful (they have therefore also originally ordered) and as far as I could see the bag is well made, but unfortunately it has no zipper. It closes with a ribbon so. I had overlooked. This then leads to that because when it appears to the sun or to the side it seems that then bad for the blanks is because light coming in (blanks not tolerate sunlight). This does not mean that bags would sunproof with zipper 100%, but in any case it is where much better (unless the "Ummaterial" is translucent, lol!). That's why I returned the bag and bought me another with zipper. Those planning the bag in a dark closet can store the bag but to buy quiet. Due to the low light protection 3 stars.
