Ok the first aid kit situation is finally solved
I ended up with a toolbox after all. Its a stanley 2-1 quick-connect. I purchased the top portion only.I can open it with one hand, its the right depth without being too shallow or deep. Will need to get either the second lower part or dividers, cause it only came with one divider
Blood type on emergency cards, yes of course.I know its nowhere on my medical records thanks Namelus
