Only 10 dollars and it’s amazing. There is a lot of storage inside but it can fold into itself to make it easier to store in a backpack. The material seems very durable. The zipper is also durable. There is a thick metal piece on either side of the zipper which makes it a lot easier to zip and provides good stability. There are some small pockets inside the pouch. I found that lead and a glue stick can fit inside these. As well as a small bag of tissues.
