I've bought several based on the recommendations and none fit!** A: If you search for this PEN-NITE-NTP31 you will find it with several replacements to choose from. **Q: can you put a space pen refill in this?** A: This pen uses the standard Parker-style refill. As long as the FIsher refill has the Parker adapter it will work **Q: where is pen manufactured?** A: Well since Nitecore is a Chinese company, I’m assuming China. I don’t have the original box so that’s my guess. **Q: Will the refill black-p900-fine tip schmidt parker style ballpoint refill work in this pen?** A: I believe that’s the same as a Parker refill so yes. I did have an issue with the bolt action though. Due to the aluminum body, it wore out quickly and wouldn’t stay open ## Frequently Bought Together - Nitecore NTP31 Bolt Action Tactical Pen with Tungsten Steel Glass Breaker with NitecoreSt Sticker - Nitecore MT2A Pro EDC Flashlight, 1000 Lumen, USB-C Rechargeable, 2X AA Battery Compatible Slim Penlight, Including NitecoreS Sticker --- ## 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/595310494-nitecore-ntp31-bolt-action-tactical-pen-with-tungsten-steel-glass](https://www.desertcart.jp/products/595310494-nitecore-ntp31-bolt-action-tactical-pen-with-tungsten-steel-glass) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-20*
