The Hearts-a-Plenty 3-D Pop-Up Bigz XL Die is part of the Valentine Collection by Sizzix. The die measures 6" x 13 3/4" and can cut many thick materials, including cardstock, leather, chipboard, fabric, foam, magnet, metallic foil, paper and more. Bigz XL dies are designed for use with the BIGkick, Big Shot and Vagabond machines only and require an Extended Cutting Pad and an Extended Crease Pad. Extra-strong, double-sided tape is required for assembly. All items are sold separately. The smallest card size that will conceal the pop-up is A2 (4 1/4" x 5 1/2"). Cards are not included. The approximate assembled measurement of this die-cut shape is 9 1/2" x 2 3/4" to 1 3/8" x 1 1/4".
