I love the soft pink colorβ€”it looks great on my desk and adds a fun touch without being distracting. The buttons are big, well-spaced, and very easy to press, which makes using it comfortable and satisfying, especially for longer calculations. The display is large and clear, so numbers are easy to read, and everything responds quickly with no lag. Brightness of numbers looks good. It feels sturdy and well made, not flimsy at all, and the mechanical-style buttons have a nice click to them. I also appreciate that it doesn’t slide around thanks to the rubber feet on the bottom. Overall, this is a great everyday calculator that combines function with a cute aesthetic. Perfect for work, school, budgeting, or even just keeping on your desk. Definitely worth the price and I’d highly recommend it. ## Frequently Bought Together - Mr. Pen Mechanical Switch Calculator - 12 Digit Large LCD Display, Pink with Big Buttons - Office Mousepad with Gel Wrist Support - Ergonomic Gaming Desktop Mouse Pad Wrist Rest - Design Gamepad Mat Rubber Base for Laptop Computer -Silicone Non-Slip Special-Textured Surface (01Pink) - Der Rose Set of 2 Succulents Plants Artificial Mini Fake Succulents Plants for Office Desk Accessories for Women Pink Home Decor --- ## 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.hk/products/550859287-mr-pen-mechanical-switch-calculator-12-digit-large-lcd-display](https://www.desertcart.hk/products/550859287-mr-pen-mechanical-switch-calculator-12-digit-large-lcd-display) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-07-03*
