In the front two exterior pockets, the sewing kit fits in on the left and the Knipex fits in the right.
It's basically a mini commonly used hardware and medication pouch. I use fishing line for sewing in situations where I need strong thread, and I have various size needles in there too. The Altoids Smalls tin has a few of my most commonly used medication for me and my family. The Rolaids are for my heartburn unfortunately.
It's just picture frame type wire which is super cheap and super strong. I have a lot of it at home, and I've had to replace it a few times now. If I didn't already have a lot of it though, I wouldn't go out of my way to carry it because strong paracord or thin rope could be just as effective.
