Review: Great - High quality Review: Works perfectly with pen from same brand - I recently bought a (very good) pen from this brand so also ordered these ink cartridges. They are well priced and come in three separate boxes which is ideal. They are easy to insert, just give the pen a gentle shake over scrap paper to get the ink flowing. Perfect fit! The ink quality is good, and a true deep black. In my pen it flows smoothly, and writes really well. I'm pleased!

Shame that there isn't a better choice of colours for business use such as blue-black, especially when Hongdian makes a blue-black ink in bottled format. ## Frequently Bought Together - Hongdian Fountain Pen Ink Cartridges Black Color Set, Pack of 30 Ink Refill Cartridges, 3.4 mm Bore Diameter - Matte Black Forest Fountain Pen Extra Fine Nib Classic Design with Converter and Metal Box Set by Hongdian --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/179373944-m2-ink-cartridges](https://www.desertcart.at/products/179373944-m2-ink-cartridges) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-22*
