Thank you for viewing. This is a cardboard sheet, 141x134mm. Thickness: 1mm 20 sheets for 300 yen You can use it for cardboard crafts or for packaging to prevent cards and stickers from bending by sandwiching them between two sheets. I try to cut them as neatly as possible, but since they are cut by an amateur, some may be slightly bent or slightly different in size, so please refrain from purchasing if you are looking for a perfect product. I will pack them in a bag to prevent them from getting wet. #Cardboard #Thick paper #Cardboard #Cardboard sheet #Cardboard pad #Corrugated cardboard #Packing material #Craft #Cardboard sheet #Pokemon #Pokemon card #Pokemon card #Yu-Gi-Oh Cardboard pad Packing material Kraft board Folding Poskit POSKIT
