PN-2891 12-Digit Scientific Calculator with 240 Functions - A Stylish Accent for Your Desk!
Product Details
This is a scientific calculator from a Chinese manufacturer.
I barely used it, so I'm looking for someone who will use it.
It has a stylish exterior, so it can also be used as a desk accent.
I will include a Japanese instruction manual and a of the instruction manual for Casio's scientific calculator fx-290, as the operation methods are likely very similar. Please use it as a reference.
It uses two LR44 button batteries (available at 100-yen shops).
Currently, there are no issues with the display, key operations, or functionality. However, please understand that I cannot accept returns or complaints.
Thank you for your consideration.
