I think this is the first Hello Kitty item I ever owned! It is a small mirror with a comb inside and Hello Kitty and Mimmy are doing each other’s hair.  Sanrio continues to make mirrors in the same small pocket size as this one. Some have combs and others are just mirrors. This retro mirror has survived incredibly well! I guess it is the wonders of plastics! haha. Click the pictures to enlarge.
