I bought this a while ago and used it at work (a home center) for about two months. It doesn't have a strap. I used a carabiner, so the original carabiner is not included. It has five pockets. The size is width 170mm x height 200mm x depth 40mm. It's a bag like a sacoche. The material is polyester. It has been stored at home, so please refrain from purchasing if you are sensitive to used items.
