Give your teacher a heart attack as he/she sees you with this Syringe Pen that uses red liquid to resemble human blood, swishing around whenever you write. Great for “injecting” some life into otherwise what is interpreted as boring texts. Definitely a great “back to school” gift, and I predict this would be extremely popular among the juveniles. It’s the novelty factor that made me buy the idea – what about you?
