The signifier of a battle well-fought and survived (despite the odds) is a bandaid across the nose
whether the wearer is 19 or
or forty-seven or
just generally
cute.
Law,
despite having a bear, just might not be cute enough for a bandaid across his
nose.
OR those plasters on Law’s face are Bepo-sized, and Bepo
tried, oh yes he tried, to put one on the bridge of Law’s nose, but Captain’s such a spoilsport, and wouldn’t let him (furthermore, considering the size of the plasters, they might’ve asphyxiated him if placed across the proboscis).

As an aside, can you imagine Daichi, the One Piece version of the Johnson & Johnson rep (or whoever’s most famous for Band-Aids in your country), trailing Luffy from island to island, battle to battle, war to war, trusty selection of bandaids at hand, because wherever the Straw Hats are there’s a need for cute plasters,. (Ace and Yamato were pre- these shenanigans), so, in general, like the News Coo and the bounty hunters, the bandaid sales rep has untapped, whole-universe potential).
