 SCP-528 appears to be an inorganic polymer. While similar to common silly putty, SCP-528 has several differences. It has proven to be completely resistant to tearing, although indentation and apparent cuts are possible. When formed into a ball and thrown, SCP-528 bounces twice as much as the regular kind. The main difference, however, is that SCP-528 is capable of copying any picture of a human being it is pressed upon, no matter if ink is involved. Any actions taken upon SCP-528 affect the individual pictured as well, usually resulting in the death of the pictured individual.
