I’ve never looked for the stuff myself before today, having only encountered it in letters from foreign correspondents (MANY years ago).
But someone asked for it on freecycle, saying she absolutely cannot locate anyone selling it in Atlanta. So I started searching.
The only stuff I can find for sale via Google is from Sanrio. Ick.
Surely this stuff can’t be that hard to find, even in the States. Surely.
Suggestions?
