Natural Beauty Meets Function.

We wanted to create an electronic calculator that would fit into an elegant, high-end workspace.

It is our pleasure to introduce a calculator worthy of the Sui Series name.

This premium calculator features the incredible beauty of the aluminum bodies that the Sui Series is famous for.

Your Choice of Functional Beauty or Flat Design.

Select between two types of keys: our gently concave curved keys offer comfort and ease of use, while our flat design keys provide a clean, streamlined look that you'll love.

Delicate Hairline Finish.

The surface of each President Calculator is brushed to create a finish of beautiful lines even thinner than human hairs. This exquisitely subtle finish maximizes the natural luster of the aluminum, giving it a gorgeous yet tastefully subdued look and feel.

Elegant Luxury Even Before Opening the Box.

All of our products arrive in exceptional packaging featuring the Sui logo.
They make the perfect present to show your appreciation.

We can even print the design or message of your choice on the surface of the beautiful paulownia wood box.
