Using this tool wrap bag is super easy. First, if you got the kit with 20 tools, you can start by placing each tool in one of the 20 individual sleeves. Make sure the tools don't exceed the 18 - inch length limit. When you're going on a bike ride, you can fold the bag up and take it with you. If you're in the workshop, you can hang it up using the grommets or lay it flat on a table. For maintenance, just wipe the bag with a dry cloth every once in a while to keep it clean. Be careful not to overstuff the sleeves as it might damage the hook - and - loop closure. Also, don't expose it to extreme heat or cold for long periods as it could affect the bag's durability.
