The Ultra-Thin Box is 2/3 the height of regular boxes so you can have more lure options in less space. It is the same size as our normal Large Box. The Ultra-Thin is great for stick and crankbaits. The box is lined with the patented Tak Logic Technology to hold your lures and other items in place. The Tak Logic Techology is scent-free, leaves no residue, easy to clean, is environmentally safe, and won't melt. The Ultra-Thin Box is made of 100% polypropylene for enhanced durability. The lid is near glass clear for easy visibility of whats inside.
