Where can I buy those cups you can eat? (Read details)

Question

When I was little, my mom would buy me these cups, and they look like normal cups...but you can actually eat them..

They are also in the Willy Wonka movie (the original)..But I have searched for them, and no luck, can anyone help? I'll give them 10 points..

Search on google, but if I am right they sell them at farmers markets. -Marty Jean Baker
