These are Flintstone Bubble Buddies that are mint on card (MOC). Shown are four of a set of six Flintstones bubblers. (I'm assuming that the six figures I have off card would be available on the cards.) The figures and bottles are made of plastic. The characters and bottle caps can be screwed off to use the bubble wands.
Cards say, "Bubble Maker, Removable Pocket Pal, Scented Bubbles (strawberry, orange, apple, and grape)." Also, "The Flintstones (TM) c. 1993 Hanna-Barbera Productions, Inc." Back of the cards say, "Dorda Toys, No. 1381."
