When you’re in the middle of a conversation, it’s not always easy to remember the specifics of your friends’ or fellow group members’ temperaments. The I Said This, You Heard That Pens can be used as a quick identifier.

Each pen is color coded and inscribed with the “language” of the temperament. If you’re using the study in a group setting, these pens are a helpful tool and a great reminder even after you’ve finished the study.

4-Pack of pens includes 1 pen of each color (red, yellow, blue, and green) and all pens contain black ink.
