As you can see in the video at the bottom, it’s not the best writing tool,
as it often drips more blood than you’d like, but the idea in itself is
enough to impress you. I don’t much like the flashy silver feather
attached, but I guess that’s just a matter of taste.This Creepy gadget
features a syringe and a pen nib, connected by a plastic
mechanism. After you fill the syringe with your own blood (seems
reasonable enough), you stick it in place and start writing your bloody
memoirs.
