All of our calculators are made of ABS plastics as they are resistant to impacts, scratches, or any sort of cosmetic wear. Different sizes make these products suitable for use in different areas, but most importantly; the office.
Small, medium, medium (wide), and large are 4 different sizes available in these calculators that can do calculations up to 12 digits. On the other hand, ergonomic buttons prevent noises that would disturb others while doing calculations. Solar energy panel and battery equipped EXXO calculators also come with a metal plate on the keyboard to reinforce durability.
