There's no size information on the box which usually means it is "standard size". The standard size for a condom varies from country to country obviously, but in all cases it's meant to account for like 90% of the male population in its sizing. So unless Watari won or lost the genetic lottery, she's fine picking normal sized ones.
Though she did pick the "ultra thin" variety, which are practically transparent they are so thin.
