It fits the Cameo3 snuggly length wise and has room on top for tools or vinyl. The front pockets will hold tools and pens nicely. The material is thin and not much help to protect from bumps but helps with taking the machine and some materials and tools on the go. Hoping this will last a few years as the Cricut duffel bag I have has been wonderfull but not much room for lots of tools and items like this bag. Will need something else to take mats and paper in.
