Hand sanitizer on school supply list

I know I’m over thinking this but which size bottle of hand sanitizer should I purchase? I always try to buy the bulk packs of items kids go through quickly such as pencils, glue sticks, expo markers, tissues, Lysol wipes, etc. This year my son has hand sanitizer on his list for 4th grade. As a teacher would you prefer 1 big bottle (67 oz) of hand sanitizer or 5 regular size (12 oz) bottles? They’re about the same price, however I didn’t know if there is a preference in bottle size, like is it easier to store multiple smaller bottles or more convenient to just set out a big bottle?
