Sanrio Hello Kitty Hana Kao Calculator. Made in 1996. This is an item from 30 years ago. Size: 12cm x 11cm Although it is a new, unopened item, it is 30 years old, and the numbers are not displaying properly! I checked the operation without exposing it to much sunlight, so perhaps⁉︎ It could be that the solar power wasn't sufficiently charged, or it could be due to aging! Since it's unopened, I haven't been able to test it by replacing the battery to fix the display. It is being sold as is! There is no guarantee that it can be repaired! This is just a casual inspection, so there may be overlooked minor scratches, etc.! Please refrain from purchasing if you are sensitive to such details! #HelloKittySolarCalculator #SanrioCalculator
