Review: Works great - I don't really see a difference between the blue and yellow under the UV light (probably because it's blue) but the pink is very pronounced. 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. Review: Cool - This is so cool! We used for a DIY escape room and it worked great!

The kids loved it ### ⭐⭐⭐⭐ Blue is messed up but they're still great markers! *by S***M on 24 April 2025* These are very fun for the price. I got them for a treasure hunt puzzle game with a group of children. The lights aren't very bright, but I was pleased that I got several for the price (and I already have a UV flashlight so it wasn't a huge loss that they aren't the best). The markers were all full of ink--none were dry. They show up nicely under the lights, especially the pink. My biggest complaint is the blue appears to be pretty much identical to the yellow? At first I thought maybe there was a mistake and the blue marker got filled with yellow ink when they were made, but the blue pen is also the most visible pen under natural lighting, so it seems to be different. All of them are a bit visible until they dry, but if you look closely you can still sort of see the blue marks hours later. I may have gotten a bad one. The other pens are great though! I definitely recommend these (especially if others are getting better blue markers), they're lots of fun. ## 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.com.cy/products/670035337-invisible-ink-pen-daemson-spy-pen-with-3-pcs-mini](https://www.desertcart.com.cy/products/670035337-invisible-ink-pen-daemson-spy-pen-with-3-pcs-mini) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-08-18*
