The Cardboard Sheet is a crafting ingredient from the BetterStorage mod. It is used in the creation of the Cardboard Box, Cardboard Armor, and Cardboard Tools. It is also used in the repairing of Cardboard Armors and Tools in the Crafting Station, repairing a maximum of 100 points of damage per sheet to all armors and tools being repaired at the time. These are its only uses.
