This is for a lot of 3 vintage 1970s Hanna Barbera Flintstones pencil toppers, and this lot includes Fred, Pebbles and Dino in blue. Measures approximately 7/8". These are a softer rubber (like a soft eraser) as opposed to being hard plastic. Some wear to opening where the pencil goes in and a little scuffing to the figures themselves. Dino has a thinning to the material on his neck.  Hard to find, as this material often decayed over time, and also these were often simply thrown out. Fun lot!
