If you're looking to secure items in your trunk, there are a few things you can do. First, you can invest in a cargo net. These nets typically attach to the sides or back of your trunk and can be used to hold smaller items in place. You can also use bungee cords or straps to secure larger items. Simply loop the cord or strap around the item and then hook it onto something sturdy in the trunk - like a tie-down anchor point. Finally, for really delicate or valuable items, you may want to consider investing in a storage box that can be securely fastened into the trunk.
