 SCP-647 is a cardboard box, appropriately sized for a 35-centimeter CRT-type television. When a live human being is within 1.5 meters of the object, SCP-647 will change its dimensions such that the subject can fit inside it easily. When a subject enters SCP-647, the flaps of the box will close and are unable to be opened. SCP-647 will secrete a digestive fluid that is absorbed by the subject's skin and dissolves soft tissues from the inside out. Once the subject is completely dissolved, the liquids are absorbed by SCP-647 and undissolved elements are forcibly expelled.
