jnzadi Retro Calculator, Made in Italy? Height: Approximately 14.0cm, Width: Approximately 10.0cm, Depth: Approximately 2.5cm Everything in the photos is included. It appears to be a calculator from the Italian brand "jnzadi," but this is not certain. The battery has leaked, and the pins have deteriorated and broken, so batteries cannot be used. It powers on with the included Japanese AC adapter, and basic operation was confirmed. As it is a very old calculator, there are fine scratches and dirt overall. Although basic operation was confirmed by turning it on, it is an old product, so no operational or quality guarantee can be provided. Therefore, it is considered a junk item. Please purchase with the understanding of this. It is believed to be a rare retro calculator. How about it for calculator collectors? Please understand that this is a used item. Please refrain from purchasing if you are seeking perfection or are overly concerned about condition.
