Man merkt aber schon anhand des Funktionsumfangs dass er schon in die Jahre gekommen ist und definitiv ein Design der 90er ist. Da ich aber Rechner sammle bin ich froh einen neuen abgestaubt zu haben. ## Frequently Bought Together - Casio FX-991MS 2nd Gen Non-Programmable Scientific Calculator, 401 Functions and 2-line Display - Casio MJ-12D 150 Steps Check and Correct Desktop Calculator --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/434966647-casio-fx-991ms-2nd-gen-non-programmable-scientific-calculator-401](https://www.desertcart.in/products/434966647-casio-fx-991ms-2nd-gen-non-programmable-scientific-calculator-401) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-07-02*
