Amo su tamaño y el color. ### ⭐⭐⭐⭐⭐ Winner of the Japanese 2024 Stationery Awards!! *by S***R on 16 May 2025* I'm so obsessed with these pens! This is the fourth one I have purchased: one for myself and three gifts. I'm very particular about my ink/ballpoint size, so I love that these are refillable with any Uniball refills. It is hard to find true fine point pens in America, so I love that these come as small as .38. They write so smooth, and the compact size makes it easy to fit in a bag. Not to mention, the short and thick shape is incredibly cute and unique. I'm shocked that these are as inexpensive as they are, given they are refillable. I've used mine for close to a year and it has held up perfectly. Also! This pen was a winner of the Japanese 2024 Stationery Awards for their design and functionality. I've included a photo of mine - it is in perfect condition despite daily use for months! ## Frequently Bought Together - uni Mitsubishi Pencil UMNSPT38M.79 Gel Ballpoint Pen Ball One P 0.38 M Savon - Mitsubishi Pencil Gel Ballpoint Pen Uni-Ball One P Rose Gold 0.38 La France UMNSPG38.76 - uni-Ball One P Bath Bomb Color Gel Ink Ballpoint Pen, 0.5mm Fine Point, M Peony, UMNSPT05M.66, 1 Count (Pack of 1) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/647677737-uni-one-p-gel-pen-0-38mm-black-ink-marble](https://www.desertcart.com.ar/products/647677737-uni-one-p-gel-pen-0-38mm-black-ink-marble) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-10-12*
