Simple and small patch indicating your blood type.Hopefully you will never need this design but if you do you will be happy you have it.I decided to make my own design because existing models where to bulky to wear them on the buckle of a helmet. I use the patches for my MTB-helmets I suppose they also work with every other kind of helmet.I would recommend eye-catching colors so that first responders can easily recognize the patches as such. (for obvious reason red/white would be fitting)For multicolor (without a system) just add a pause berfore the layers of the letters start
