Joe,
Great news for those of us who are old time candy aficionados. Some of the products you mention are still being made. Chiclets are still made; but, the Tiny Size Chiclets seems to be hard to find. Bottle Caps have changed the packages. Freshen Up Gum is still made; but, it is not easy to find locally either. I always liked Freshen Up Gum. Candy Necklaces can be found. Razzles have also changed the packages. Lik-M-Aid has changed the name. It's now called Lik-M-Aid Fun Dip.
Time to make a candy store run. However, we sure can't buy candy for 5 cents each anymore.
