I kept it inside the house. I used it as a candy container (with the candy still in the box). The ink in the bag seems to be stained only in blue, but it's been like that from the beginning. Both the outside and inside of the bag have a bit of a waterproof treatment, so it seems to be okay if it gets a little wet. The fabric is a bit thick and sturdy. The size is about 22 x 17 x 9cm.
