MOST POPULAR QUESTIONS
How do I fill the ink in my stamp?
Here are the different steps for filling:
1. Place the stamp upside down on a flat surface (the ink pad should be pointing toward the sky).
2. Remove the stamp cap and carefully pour a few drops of ink onto the ink pad (enough so that the ink pad is covered with ink).
3. Leave the stamp in this position for 10 to 15 minutes until as much ink as possible soaks into the ink pad.
4. Use a dry cloth and wipe off excess ink.
