Blood Group O Negative Card

O negative is the universal donor type and really useful in emergencies, but it's less common (about 7–13% in the UK depending on the source, often around 7–8% for the general population). Carrying a clear O- card means it's easy for paramedics or hospital staff to spot your type immediately if you're unable to communicate—whether that's from an injury, while abroad, or in any unexpected situation. This non-personalised single-sided version keeps it straightforward: bold O- display plus the essential disclaimer that full lab testing and cross-matching are always required before transfusion.

Why this one appeals to people

• Regular blood donors who want to carry their type proudly and practically

• Travellers who appreciate having key info ready in case of language barriers or different medical systems

• Anyone building a basic "just in case" kit for themselves or family members

• Those who value the peace of mind from knowing universal donor status is noted upfront
