Tried it on paper and faux leather so far and it takes a second to fade, but it isn't visible after it dries. On the paper, the pink marker left a very slight impression that you would not be able to see at a glance but if you look hard and know exactly where it is, you can see a small color difference. Haven't tested on other surfaces but so far, so good. ### ⭐⭐⭐⭐⭐ Excellent for scavenger hunts and projects *by on Reviewed in the United States 20 August 2026* These pens were magical and lots of fun and made our scavenger hunt even more exciting! ### ⭐⭐⭐⭐⭐ The Pros and the Cons (but mostly Pros) *by on Reviewed in the United States 11 June 2025* We did a scavenger hunt and this worked marvelously! We absolutely loved the invisible ink - it showed up so well!Pros:- The pens work great- The lights actually show the invisible ink.- That are durable and last well- They are just so fun!!!Cons:- The marker tips are on the thicker side so writing small is not an option.- The ink does run if it gets moist or wet.This is a great price for the awesome item you get - I would highly recommend purchasing it! ## Frequently Bought Together - Daemson Invisible Ink Pen, Spy Pen with 3 PCS Mini UV LED Keychain Flashlight, Disappearing Ink Magic Pens with Black Light Markers for Secret Notes, Fit for Christmas Halloween Holiday Gifts (3 PCS) - Moxweyeni 10 Pcs 3 Digit Combinations Padlock Safe Cipher Lock Mini Combination Resettable Number for Suitcases Luggage Briefcases Computer Bags(Cute Style,Multicolor) - Creative Hobbies Pack of 6 Ready to Decorate Wood Treasure Chest Box Savings Bank with Coin Slot, Hinged Lid and Lockable Front Clasp, DIY Craft --- ## 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.pt/products/670035337-invisible-ink-pen-daemson-spy-pen-with-3-pcs-mini](https://www.desertcart.pt/products/670035337-invisible-ink-pen-daemson-spy-pen-with-3-pcs-mini) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-03*
