Jetpens **Q: whats the plastic holder for? I want this for my small journal that has a loop for a pen, would this work?** A: OK, what they're calling a "holder" is actually a piece of plastic about the size of a credit card with a sleeve along one side in which the pen fits. I guess you put the card part between pages of a book to hold the pen there? I don't know, it doesn't seem very useful to me. As for the loop on your journal: How small are we talkin'? Because this pen is tiny. TI-NY. It is the approximate length (maybe 3") and diameter of a wooden cocktail pick. I'm not kidding. It's very small and difficult to write with - and I have small hands! As such, I can't imagine it holds enough ink to write very much. When I bought it, I was looking for something with a super-fine point that was not a gel pen, but this is actually just a super-tiny pen in all respects but was not enough of an expenditure to return it. ## Frequently Bought Together - Auto NBP-505MN-BK Ballpoint Pen, Oil-based, Black - OHTO Extremely Thin Mechanical Pencil Minimo Sharp, 0.5mm, Black Body (SP-505MN-Black) - Zebra Mini Ballpoint Pen 0.7 mm, Silver Body, Black Ink (T-3) --- ## 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.sk/products/25317725-auto-nbp-505mn-bk-ballpoint-pen-oil-based-black](https://www.desertcart.sk/products/25317725-auto-nbp-505mn-bk-ballpoint-pen-oil-based-black) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-15*
