A sterile, disposable skin-marking device for applying a marking agent to the skin of a patient who is to undergo radiation therapy. The skin-marking device has a flexible housing that contains a rupturable cartridge containing the marking agent. The application end of the device is provided with a LUER-LOK coupler. A needle of appropriate size, with a LUER-LOK base, is selected and inserted into the LUER-LOK coupler, with the sheath still intact and in place. The cartridge is then ruptured by flexing or compressing the housing,. The marking agent flows into the needle, and, after removing the protective needle sheath, the needle is used to penetrate the skin of the patient to apply the marking agent to mark treatment set-up points.
