The mesh material allows you to easily see your project, which is incredibly useful for colorwork. The snaps on the opening of the bag provide a snag-free environment and act as a yarn bowl of sorts because you can feed the yarn through the snaps and work out of it while on the go. Each Oh Snap set comes with a mini dot journal for keeping track of rows, pattern notes, etc.
