Blood Group O- Awareness Card – £4.99

O- negative is the universal donor – you can give blood to absolutely anyone, but only about 7% of people in the UK actually have it. That means when you need blood yourself, the only safe matches are other O- donors.

If you’re ever unconscious, paramedics will open your wallet looking for anything that says blood group. This single-sided card gives them the answer instantly: O- in big white letters on the red blood-cell background with the medical symbol top left.

A lot of O- people buy a few at once (one for each wallet, glovebox, partner’s car). Works out cheaper to buy than just one and then you’re never without one.
