The Tronixpro Rig Winder Box is specially designed for the Tronixpro Rig Winders and allows anglers to neatly organize their rigs. These boxes are made of sturdy and durable transparent plastic so you can quickly identify the contents. In addition to storing rig winders, they are also ideal for storing small accessories. Thanks to the raised pattern at the top and bottom, the boxes can also be easily stacked. The box holds 20 standard winders or 42 slim winders.
