Often seen in museums and the like, display cases such as these are a solid investment if you want to display any precious personal items.
These particular cases are made from Brigalow and are a complete unit without doors.
All of the corners are reinforced with splines which can’t be seen in the photographs because they are, as usual, fairly ordinary.
Personally I think they help to make the pieces stand out moreso than them being on their own. But I would say thay wouldn’t I.
