This is not only a keychain, this can be your life saver! Keep forever with you your blood type in a modern and smart way. It can be invaluable to have something with you to remember your blood type in emergencies! I personally will have this keychain with me forever. It's preferable to print in a metal material, to be indestructible.
Please choose your blood type:
0- 0+ A- A+ B- B+ AB- AB+
