rating: 0+x

Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: SCP-XXXX is to be contained inside a 15cm x 15cm x 15cm Containment unit made of lead-lined concrete.

Description:
SCP-XXXX appears to be a M██ hand grenade, the entire surface of which appears to be composed of human or animal bone and polished heavily.
The anomalous properties of SCP-XXXX occur whenever a person or object holding the entity removes the safety pin.

Any personnel that decides to remove the safety pin will discover that throwing or even removing SCP-XXXX from their body is impossible, seemingly stuck to their skin with an adhesive secreted by the entity.
After approximately 3 seconds after removing the pin, the personnel holding SCP-XXXX will then swiftly and violently combust in a 5 meter radius explosion, resulting in their termination.

The entity however, remains completely intact and the saftey pin seems to have been replaced with a different "pin" constructed from the subjects bones.

The explosion caused by SCP-XXXX has absolutely no effect on its surroundings or even the object itself, only affecting the personnel holding it.
