Description: SCP-3660 is a black metal zipper, similar to those found on sweaters and backpacks. The item is in poor condition. A significant amount of its paint has been ground off, the metal is warped and half of its slider is missing(appearing wrenched off). SCP-3660 is non-anomalous and inert until it is pressed against the skin of a human being1. The amount of force applied can be disregarded when considering an implantation event. In a manner not dissimilar to magnetic attraction.
