The hybrid ink makes it glide on paper and the only downside is it runs out too fast (1 refill every 3 weeks) ### ⭐⭐⭐⭐ Good sign pen *by I***H on 11 August 2022* Good pen for signing purpose. Its writes very bold, broad, dark and smooth. But it does not have an impression like a roller pen, in fact it writes just like a 1.0 mm ball pen like that usually cost around ₹10. Its writing smudges a lot, so you need to be careful that there isn't an accidental touch immediately after writing. Looks premium and has good grip. The refill costs ₹60 and is difficult to find. ## Frequently Bought Together - uni-ball Jetstream SX-210 1.0mm Roller Ball Pen | Blue Ink, Pack of 1 - UNI-BALL Jetstream SXN210 1.0mm Roller Ball Pen | Blue Ink, Pack of 1 - uni-ball Jetstream SX-210 1.0mm Roller Ball Pen | Black Ink, 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.jp/products/300359156-uni-ball-jetstream-sx-210-1-0mm-roller-ball-pen](https://www.desertcart.jp/products/300359156-uni-ball-jetstream-sx-210-1-0mm-roller-ball-pen) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-18*
