The brand-new Sideloading Flex Card Divider is a durable and resistant card divider that will tidy up almost any sideloading deck box. Each pack contains 10 different vibrant colors to provide a maximum of organization possibilities. The foldable register tab allows an increased height that sticks out from the cards and provides a much better visibility. The flexible fold-line makes sure that the box can be closed. The register tab will just fold to the side and unfold when the box is opened.
