I think Enrique misread it and it's Guest Papers. What the thoughtful host puts out for their guests to doodle on when the conversation gets boring.
Of course Enrique shrugs and tells his guests to help themselves to anything from his cupboards, which have nothing in them but Pot Noodles, so he wouldn't know anything about that.
