It’s a box full of items to repair a tire. Everything you need is in the box, aside from some water and soap to find the leak. I had a screw on my tire, I popped it out with the pliers that it comes with and used the tools to clean the puncture and then plug it. Even someone who doesn’t know what they’re doing can do it. Tools seem like good quality and it comes with extra metal pieces in case the originals break and don’t work well. It does the job.
