I don't know if it will help you but they have them at
Norwood Drugs 6165 N. Northwest Highway
773-631-5333
But definately phone first.
Also I've seen them at grocery stores but they come
in a white box, Old Londen product I believe.
I like the cartoon little beatnik guy with the horn and
singing? skat on TV in the ads late 50's early 60s.
