I have never had any fading problems. But, I can not state that they are 'archival quality' But, I do love the pens, and I have papers 2-4 years old with no fading. **Q: Are these 0.7? Description says they are, but picture shows 0.5.** A: Of the pictures shown only one is showing up as 0.5 and it won't allow me to zoom in. I believe it might be an error showing the wrong pen. The other clear picture, that's zoom-able, is clearly showing 0.7. I don't recall ordering any 0.5 pens. I only have the 1.0 and 0.7 sizes. I still have a few dozen pens left. They never stop working until they completely run out of ink. I prefer the smoother 1.0 size personally. The 0.7 is great for when I need clear precise writing in very small spaces. Great pen! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Smoothe, well contructed and will take refills *by N***S on 10 September 2025* Great pens. Smoothe, and can write upsidedown and in the rain as advertised. Both the 1.0mm and 0.7mm write smoothly and are well-balanced. The ink cartridges are large and last longer than average pen. My daily go-to. ### ⭐⭐⭐⭐⭐ Pessurizadas *by A***O on 31 May 2026* Ótimas canetas que não falham ### ⭐⭐⭐⭐⭐ Great pen, equal to a fisher at a fraction of the price *by S***I on 24 September 2025* I love these pens. I found them years ago when I used to travel to Japan and then forgot about them. I have several Fisher space pens but it's a real pain in the butt when you lose one of these because they aren't cheap. These are the equivalent in a throwaway form factor. They aren't so expensive that you cry when you misplace it or somebody walks off with it. It writes upside down and on wet things just like a fisher space pen without the exorbitant cost. They are comfortable and the fine point works very well, never clogs never gets scratchy. I love these, and everybody that tries one usually wants to walk away with my pen. If I like them I let them because at this price I can buy several at once. ## Frequently Bought Together - Uni-ball Power Tank Ballpoint Retractable & Fine Ballpoint Pen Rubber Grip Type-0.7mm-black Ink-value Set of 10 - uniball Power Tank Rt Ballpoint Pen, Retractable, Bold 1 Mm, Blue Ink, Translucent Blue Barrel, Dozen - 三菱鉛筆 Mitsubishi Pencil SN200PT07.33 Pressurized Ballpoint Pen, Power Tank, 0.7, Blue, 10 Pieces --- ## 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/268180807-uni-ball-power-tank-ballpoint-retractable-and-fine-ballpoint-pen](https://www.desertcart.jp/products/268180807-uni-ball-power-tank-ballpoint-retractable-and-fine-ballpoint-pen) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-16*
