Abstract

A kit for applying stamping identification onto compact discs includes a base for supporting a compact disc, and a hand stamp with a spring loaded spindle sized to fit into a hole in the base for centering the stamp relative to the disc. The spring force on the spindle must be manually overcome to apply the stamp to the disc and helps maintain uniformity of stamping force. The stamp assembles with an inkwell unit for clean and convenient storage of both stamp and inkwell.
