The
secret pocket spell creates an extradimensional space that only you can reach through a pocket in the
target garment. The
secret pocket can hold 1 pound per caster
level, and you can put anything in it that will physical fit through the pocket opening. The item can be of any length and isn't otherwise restricted by the pocket's actual dimensions-it just has to be able to fit through the opening. The contents of the extradimensional space never cause the pocket to bulge, and items inside the
secret pocket have no weight once they're placed inside (although the weight still counts against the capacity of the extradimensional space). Whenever you reach into the pocket, you access the extradimensional space rather than the actual pocket. Anyone else who examines the pocket finds it completely ordinary. If someone else puts something in the pocket, you can't reach it because your hand goes into the extradimensional space instead.
You can give the garment to someone else to wear if you like, but only you can access the extradimensional space through the pocket.
