It's an envelope of fabric from Japan, a very small envelope with rather alot of stamps - with even more on the front!
How beautiful to see proper stamps instead of the impersonal package labels we now have in the UK.
It immediately sent me on a nostalgic trip down memory lane, to my 70's childhood and stamp albums, full of colourful stamps from those magical, faraway lands.
Whatever happened to stamp albums? I wish I still had mine.
