Abstract
A small object handling device composed of an elongated rod with a wax composition coated over one end thereof. The invention further comprises an assembly of small object handling devices, with each composed of an elongated rod having a pressure sensitive adhesive composition coated over one end, and with the opposite end connected to a common rack. A flexible strip may cover the common rack and rods to protect the pressure sensitive adhesive ends of said rods and to provide a matchbook-like appearance. In an alternate embodiment, the device has a tubular member filled with pressure sensitive adhesive, with a rod adjustably coupled to one end of the member for forcing the pressure sensitive adhesive out from the opposite end. The method of the invention involves dipping each rod into a liquid bath of pressure sensitive adhesive at a maximum temperature of no more than 140 percent of the melting temperature of the pressure sensitive adhesive, removing each rod from the liquid bath with a coating of pressure sensitive adhesive surrounding the immersed end, and allowing the coating to cool and harden on the rod.
