Art Nouveau razor or toothbrush box, T mark

I wonder what the holes in the lid are for?

Have a funny feeling it could be French,
from somewhere like Sarreguemines.

Evaporation?

Pot pourri or such like?

I was just wondering the same thing.
Perhaps it's for that orange peel could start filling it up, to test.

Peel your orange with a razor. Then use the soap to clean the resulting injuries. Victorian multi-utility obect!
