The Jam ‘N Shred Pen is another cool product by Girl Tech.Â It’s a unique pen that consists of 3 practical uses. First of all, it’s got a built-in radio so you can listen to the radio while you write- an earbud is attached at the top for listening. But here is the kicker – the pen has a built in note shredder. That makes the Jam ‘N Shred Pen perfect for passing notes so that you can shred the evidence right after you’ve read the note. The Jam ‘N Shred Pen retails for just $8.99 and it’s also designed to fit in the Girl Tech Password Journal.
