Solar Calculator Diary

This image features a set of three calculator notebooks with a vibrant, ombre aesthetic. These unique stationery items combine a spiral-bound notebook with a fully functional, solar-powered calculator integrated directly into the front cover.

Key Features:

• Integrated Calculator: The cover features a digital display screen and a touch-sensitive keypad with standard mathematical functions (addition, subtraction, multiplication, division, percentage, and square root) along with memory keys ($M+$, $M-$).

• Design: Each notebook has a distinct gradient color scheme, including a blue-to-pink ombre, a green-to-red ombre, and a light blue-to-white ombre.

• Binding: The notebooks are held together by a durable silver metal twin-loop spiral binding, allowing them to lay flat when open.

• Versatility: This 2-in-1 design is ideal for students, professionals, or anyone needing to perform quick calculations while taking notes.
