Transformation Pen's are the first devices used by the Inner Senshi to transform into their Senshi identities.


Ami won her mystical Transformation Pen by playing the Sailor V game. Luna gave Rei and Makoto their transformation pens, and Artemis was the one who gave Minako her pen, all pens look identical except Minako's, as hers was a different style more like a pencil with a cap and a star on the top.

Each pen has different color similar to the senshi who is using it. It also has a planetary symbol on top.

When the Transformation Pen's were destroyed in the battle with Queen Metaria, they were replaced with the even more powerful Star Power Sticks.
