Key Features

• 2-in-1 Calculator + Reusable Writing Tablet: The scientific calculator and LCD notepad are integrated into a single foldable device — write your workings, intermediate steps, and notes directly on the LCD surface while using the calculator simultaneously. No more juggling a separate notepad and calculator during exams, study sessions, financial calculations, and construction work
• Blue Matte LCD Screen — Eye Protection: The blue matte LCD writing surface is specifically designed to reduce eye strain during extended use — the matte finish eliminates glare and the blue-tinted display is gentler on the eyes than standard LCD screens during long study sessions, office work, and late-night calculations
• Reusable — Eco-Friendly, Zero Paper Waste: Press the clear button to instantly erase all LCD notes and start fresh — write, erase, and rewrite indefinitely without paper, ink, or dust. Reduces paper consumption, eliminates the need for notepads, and protects personal privacy by instantly erasing sensitive calculations and notes
• 3 Scientific Calculation Models: Available in three calculation method configurations — MS349 (computing methods), ES417 (calculation methods), and CNX498 (calculation methods) — each offering a different set of scientific functions suited to different academic levels, professional disciplines, and calculation requirements
• Portable — Folds Flat for Bag, Pocket & Wallet: The foldable design collapses flat for easy carrying in a school bag, briefcase, jacket pocket, or even a wallet — always with you for instant calculation and note-taking access during classes, meetings, site visits, and travel without carrying a separate calculator and notepad
