Sizzix ScoreBoards XL Die - Box, Square by Eileen Hull
If it's chipboard or mat board, then ScoreBoards XL dies expand your creativity with quick and easy cuts and scoring. The first-ever product of its kind, ScoreBoards dies produce sturdier boxes, pockets, holders and other ultra-versatile designs.
Compatible with the BIGkick, Big Shot and Vagabond machines (with a pair of Extended Cutting Pads), ScoreBoards easily cut and score most mat board and chipboard. (Use board thickness from .040" to .055" for best results.) Extra-strong bond, double-sided tape is required for assembly.
