While these cell phone charms might seem kind of gruesome at first, they can actually be quite useful in an emergency situation. The cell phone ‘blood bag’ strap, besides providing a definite conversation starter, indicate your blood type.
They play an even more interesting role in Japan where it is believed that your blood type can be indicative of your personality.
Available at Strapya World for $5.82, it’s small price to pay for what could start the best conversation you’ve ever had, or potentially even save your life!
