New sealed package of a candy the Internet has almost forgotten - but your taste buds haven?t! Belongs in a museum, or maybe the last Blockbuster. No expiration date, but obviously cannot guarantee they are still good after all these years. Were they ever, really? Please purchase for the nostalgia and not the health benefits. Some minor damage to cardboard from being in a cupboard for 20 years. My grandmother thought they were sour food coloring and never used them but also didn?t want to throw them away. I promised to buy her new food coloring if we sell them. :) Discontinued Ice Drops Sours Xtreme Liquid Candy Red Blue Green Y2K Nostalgia.
