ScrapRack Dividers - 5pk are made of translucent, semi-rigid plastic. These dividers identify your major categories, making it easy to find the supplies you need. Each divider has a large labeling tab, five positions in all. TIP: When adding your final category titles, label BOTH sides of your Divider tabs so you can see the titles regardless of which side of the Divider you're looking at. Because they are larger than the ScrapRack Storage pages, Dividers help to protect the edges and corners of your ScrapRack pages and all the products they contain. Don't worry - your Canvas Craft Binder, Big Fat Flippin' Storage Binder, and Spinder Binder will still zip easily around the dividers on the Spinders you take with you. Dividers also help to provide stability to your filled ScrapRack pages and supplies. Add two to three Dividers per Spinder for best results.
