The eyeliner doesn't transfer?
If it's not transferring it could be your eyeliner. If it has a high alcohol content it will dry before getting it to your eye. What you can try is clean the tool completely and allow it to dry. Once it it dry, apply a single layer of eyeliner to your tool and allow that layer to dry for 30 seconds. After it has dried, apply a second layer of eyeliner, and stamp it on. The first coat should hold the moisture from your eyeliner for longer allowing you enough time to stamp it on. If this problem still persists you may want to try a different eyeliner.
