Each pen comes with batteries installed, so there is nothing extra to buy. Designed for children ages 3 and up, these pens work on paper, skin, fabric, and most surfaces without leaving a permanent mark. The ink is tasteless and washes off easily, making them a safe choice for birthday parties, treasure hunts, escape rooms, and classroom games.\u003c\/p\u003e\n\n\u003ch2\u003eHow do these invisible ink pens work?\u003c\/h2\u003e\n\u003cp\u003eWrite your message on any surface using the disappearing ink. After a few seconds, the ink fades and becomes invisible. To read the secret message, simply shine the purple LED light built into the pen cap. The light reveals the glowing ink, and the message is visible again until the light is turned off. It is a simple, no-mess way to create spy missions or hidden clues.\u003c\/p\u003e\n\n\u003ch2\u003eAre these pens safe for kids?\u003c\/h2\u003e\n\u003cp\u003eYes. The ink is non-toxic and tasteless, and it washes off skin, clothing, and surfaces with soap and water. However, the pen contains small parts (batteries) so adult supervision is recommended for children under 3. The pens are suitable for kids aged 3 and older, teens, and even adults who enjoy party tricks or scavenger hunts.\u003c\/p\u003e\n\n\u003ch2\u003eKey details at a glance\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eiGeeKid\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWriting Instrument Form\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMarker Pen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eColor\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMulticolor (assorted)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInk Color\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMulticolor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAge Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eKids \/ Teens \/ Adult\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePack Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e32 pens\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLight Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBuilt-in purple UV LED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBattery Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eButton cell (replaceable, included)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eHow long does the battery and ink last?\u003c\/h2\u003e\n\u003cp\u003eThe purple LED light is designed for long use, and the button cell battery can be replaced when it runs out. The ink itself does not evaporate quickly under normal use, so you can use the pens over many play sessions without running dry. For best results, store the pens with the cap on to keep the ink fresh.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eCan the ink be seen without the UV light?\u003c\/h3\u003e\n\u003cp\u003eNo. The ink is completely invisible once dry. Only the purple light from the pen cap makes the message glow, so the message stays secret until you reveal it.\u003c\/p\u003e\n\u003ch3\u003eDo these pens work on any surface?\u003c\/h3\u003e\n\u003cp\u003eThe ink writes smoothly on paper, skin, fabric (like t-shirts), and hard surfaces. It washes off easily from most non-porous surfaces and clothing with water.\u003c\/p\u003e\n\u003ch3\u003eAre these pens good for party favors?\u003c\/h3\u003e\n\u003cp\u003eYes. With 32 assorted-color pens, they are ideal for goodie bags, birthday parties, 4th of July celebrations, and classroom exchanges. Each pen is a self-contained spy tool that sparks imaginative play.\u003c\/p\u003e","brand":"iGeeKid","offers":[{"title":"Default Title","offer_id":58079672926511,"sku":null,"price":27.97,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/4478\/7503\/files\/igeekid-32-pack-invisible-ink-pens-with-uv-light-secret-spy-pens-for-kids-disappearing-ink-markers-for-treasure-hunts-party-favors-and-classroom-activities-1.jpg?v=1781621776","url":"https:\/\/toysforkid.co.uk\/products\/igeekid-32-pack-invisible-ink-pens-with-uv-light-secret-spy-pens-for-kids-disappearing-ink-markers-for-treasure-hunts-party-favors-and-classroom-activities","provider":"Toys For Kid","version":"1.0","type":"link"}
