What six items does George put on his shelf?

In Chapter Two of Steinbeck's "Of Mice and Men" George and Lennie enter the bunk house where George is suspicious of bugs when he finds insect repellent.  But, after the old swamper reassures him that the last occupant was clean, George sets his possessions on a shelf:  razor, bar of soap, comb, bottle of pills, liniment, and a leather wristband. These are his simple, bare necessities.
