As with any new stamp set or design stamp, please practice with these stamps first on some copper sheet before stamping on sterling silver.
These stamps come packed with a light coat of oil to prevent rusting. When you first open them, have a few paper towels handy and just wipe them all clean (do not use any water).
The stamps are not marked to help with orientation. The first time I
used them, I used a black permanent pen (or a white paint pen if the stamp is black) and put a dot on the side of
the stamp where I should hold my thumb to ensure the letter would be
facing the correct way.
