This is a perforated cardboard material that can be used for packaging trading cards. By folding it in half, you can protect both sides. There is a perforation in the center, so you can use it either folded or separated. Number of sheets: 26 + 4 spares (60 sheets total when separated) Size: 200 x 80mm (perforation in the center at 100mm) Thickness: 1.5mm The surface will be protected with 4 spare sheets instead of cushioning material, and it will be shipped via Mercari mail in an OPP bag to prevent it from getting wet. I also have other quantities available, so please consider them. ☺ For trading cards, for trading card packaging, for cards, for card packaging
