There is a collector of blade here in Canberra I've met up with and he has some in albums and other framed on the walls. The ones on the walls are in A4 frames from stationery suppliers or BigW or wherever with a sheet of 'magnetic paper' glued to the backing board, something like this, the sort of stuff you see on fridge magnets.
He was then able to arrange the blades as he wanted in the frame
mate that's perfect! especially for the loose single blades I have that I want to display. the packeted ones I think I'll put them in the glass display cabinet scattered in between my razors that I have on display.
cheers mate!
