Description The most popular add-on from the incredibly successful Kickstarter campaign will now be available in sideloading format! The Sideloading Sizemorph Divider, our brand-new innovation, is probably the first divider on the market that can change its width to fit into almost any unused horizontal box space. It is a perfect match for all sideloading boxes and tidies up your deck box! No matter if you want to fill up space between two decks of cards or keep your deck boxes safe. Its width can vary between 5 and 30 millimeters, allowing maximum flexibility. The foldable register tab will bend back and unfold when the box is opened.
