Am I the only one who has been frustrated by the dearth of writing instruments that are both comfortable and allow you to write in your own blood? I mean, how many confessions of undying affection have been botched for want of an adequate instrument to scrawl, in your own blood, in an even and steady flow "I will never leave you"? Too often the script becomes splotchy and the blood text reads something like "I Uoll NBeBR LEave yUU" which is just creepy. Thankfully, the problem is now solved with this blood pen.
