In France, I always go to the pharmacy and buy URGO band-aids. Actually, they are called Urgo"discret transparent et esthetique."
These are the best band-aids in the world. They are packed well , they stick well,and don't cause rashes. They are described as
"hypoallergenique." I have also found them in Italian pharmacies. There is no acceptable substitute. Blisters on your feet from walking--go for the URGO!
