They were originally assembled using glue, wooden pegs, and square head nails, although many of these were replaced at some point with early round head nails.

Condition is quite good with some age-related separation of wood as seen in photos---nothing that disturbs the structural integrity or visual appeal of this very early pair. Both retain wonderful, all-original patina. Please see photos for a fine representation of all angles and insides and outsides of both boxes. The covers of both boxes fit nicely despite the crooked appearance suggested in my photos!
