Hello Kitty calculator, stored at home for a long time. Unknown if it has been used. Since there are no spare button batteries and I cannot confirm its operation, I am selling it as junk. Batteries, the area where the batteries were, and a green paint-like substance are attached (Image 9). The box is crushed. There may be other overlooked issues during inspection. Please consider this before purchasing. It will be shipped via Yu-Packet Post Mini, etc.
