It's a piece of cardstock 7 X 2 3/4 - score at 3/4", 3 1/4" and 6 1/4" (this will make one side bigger to accomodate the PB cup and have it stand up). Tape the bottom two flaps together. Then I punched holes in the front to slide the pencil through. If I did them again, I might punch the holes up and down instead of side to side. Live and learn.
