The pen has a removable cap with an atypical clasp. **Q: Is the pen with the label "umr-1" and the pen with the label "um-151" the exact same pen?** A: The pens I purchased carry both labels on them. I am not aware of pens with just one of those two label references. **Q: Do these ship directly from Japan?** A: Yes **Q: Is this fake? Because I have the original one from a japanese store it doesnt have the chinese symbol on the cap.** A: Not sure what you mean by "fake". I've purchased and repurchased these wonderful pens through Amazon and this dealer, no problems. Mine show Japanese symbols on the pen shaft, not the cap. ## Frequently Bought Together - uni-ball Signo Dx Um-151 Gel Ink Pen - 0.38 Mm - 10 Pcs - Black - Uni Mitsubishi Pencil - MAIKEDEPOT Felt Tip Pens, 15pcs Calligraphy pen Assorted Colors Sign Brush Pen Art Brush Marker Water Based Journaling Pen Set for Beginners Beginner Adult Lettering, Calligraphy (15pcs) - SAKURA Pigma Micron Fineliner Pens - Archival Black Ink Pens - Pens for Writing, Drawing, or Bullet Journaling - Assorted Point Sizes - 6 Pack --- ## 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.sn/products/1482177-uni-ball-signo-dx-um-151-gel-ink-pen-0](https://www.desertcart.sn/products/1482177-uni-ball-signo-dx-um-151-gel-ink-pen-0) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-15*
