Okay to purchase immediately. This calculator can perform calculations up to 12 digits and includes tax calculation functions. I used it about five years ago when I was studying bookkeeping for about six months, but I've kept it stored in a dark place since then. Operation has been confirmed. As it is a used item, the picture on the sticker has peeled off a bit, but the main body has no noticeable scratches. I think it can be used cleanly if you remove the sticker. When packaging, I will wrap it in bubble wrap and put it in a bag before shipping it via Yu-Packet. - Model Name: My Melody Calculator - Color: Pink/Light Blue - Features: Cute design, with decorations - Function: Tax calculation function available - Number of Buttons: Large buttons
