These pens are so cheap the battery would probably cost more than a new pen! **Q: Do they have enough ink to last long?** A: Your question depends on the user - my guess is, the ink will last about as long as any other thin tipped felt pen. If you're planning to use these as security measure against fraudulent returns, its more likely you'll leave the cap off sometime over the next year causing the pen to dry out, long before it would run out from use. **Q: How bright does it show up** A: Not very bright in my opinion. **Q: How big are they?** A: Each pen, including the light on top, is about 5 inches long. It's about as thick as a standard "stick" pen, but the top (about 1 3/4 inches) with the light in it is wider, maybe a half inch in diameter. ## Frequently Bought Together - KERRT Invisible Ink Pen with UV Light Secret Message Pen Spy Pens Magic Invisible Markers Classroom Gifts for Students, Party Favors for Kids 8-12, Goodie Bag Stuffers for Kids - Lighting EVER Black Light Flashlight, Small UV Lights 395nm, Portable Ultraviolet Light Detector for Invisible Ink Pens, Dog Cat Pet Urine Stain, AAA Batteries Included --- ## 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.com.pa/products/39786726-invisible-ink-pen-with-uv-light-secret-message-pen-spy](https://www.desertcart.com.pa/products/39786726-invisible-ink-pen-with-uv-light-secret-message-pen-spy) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-10-18*
