With eight neon colors and four pens per shade, the set is designed for group play, party favors, and detective-themed activities for children ages 6 to 12.\u003c\/p\u003e\u003ch2\u003eWhat Comes in the Box\u003c\/h2\u003e\u003cp\u003eThe complete set includes 32 pens, evenly split across eight colors. Each pen has a small UV light in the cap to reveal the ink. No batteries, extra lights, or special paper are required — everything works straight out of the package.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e32 pens total (4 per color)\u003c\/li\u003e\n\u003cli\u003e8 colors: the exact shades are not specified, but the set offers a rainbow of options\u003c\/li\u003e\n\u003cli\u003eBuilt-in UV light in every pen\u003c\/li\u003e\n\u003cli\u003eNon-toxic invisible ink\u003c\/li\u003e\n\u003cli\u003eSuitable for ages 6 and up (per manufacturer recommendation of over 3 years)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow the Invisible Ink Works\u003c\/h2\u003e\u003cp\u003eWrite a message or draw a picture on any light-colored paper. The ink dries clear and invisible to the naked eye. To read the secret message, switch on the UV light in the pen cap and shine it over the writing. The ink fluoresces under the light, making the hidden content visible. The effect works best in dim or dark conditions.\u003c\/p\u003e\u003ch2\u003eWho Would Enjoy These Pens?\u003c\/h2\u003e\u003cp\u003eThese pens are a natural fit for mystery-themed parties, spy games, and treasure hunts. Teachers often use them for classroom rewards or creative writing prompts. The set is equally popular as Halloween goodie bag stuffers, Christmas stocking fillers, and birthday party favors. Because each child gets multiple pens in different colors, the set works well for groups and classrooms.\u003c\/p\u003e\u003ch2\u003eUsing the Pens with a Group\u003c\/h2\u003e\u003cp\u003eWith 32 pens, there are enough for a class of 25 plus extras for the teacher. The eight colors allow kids to code messages by color — for example, blue ink for clues, green ink for answers. The UV light in each pen means every child can read and write independently. No additional supplies are needed.\u003c\/p\u003e\u003ch2\u003eAre There Any Safety Concerns?\u003c\/h2\u003e\u003cp\u003eThe ink is described as non-toxic and child-safe. The pens are recommended for children over 3 years old. As with any small object, supervision is advised to prevent accidental ingestion of the cap or pen parts. The UV light is low-power and safe for occasional use, but it should not be shone directly into eyes.\u003c\/p\u003e\u003ch2\u003eQuick Specs\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal pens\u003c\/td\u003e\n\u003ctd\u003e32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColors\u003c\/td\u003e\n\u003ctd\u003e8 (4 pens each)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUV light\u003c\/td\u003e\n\u003ctd\u003eBuilt into each pen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInk type\u003c\/td\u003e\n\u003ctd\u003eNon-toxic invisible ink\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended age\u003c\/td\u003e\n\u003ctd\u003e6–12 years (per product description)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSafety notes\u003c\/td\u003e\n\u003ctd\u003eOver 3 years; non-toxic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eTIDALJAM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eDo I need extra equipment to reveal the messages?\u003c\/h3\u003e\u003cp\u003eNo. Each pen has a built-in UV light, so the pen itself is both the writer and the reader.\u003c\/p\u003e\u003ch3\u003eHow many pens are in each color?\u003c\/h3\u003e\u003cp\u003eThe set has eight colors, with four pens per color, for a total of 32 pens.\u003c\/p\u003e\u003ch3\u003eIs the ink safe for children?\u003c\/h3\u003e\u003cp\u003eThe manufacturer states the ink is non-toxic and the pens are recommended for children over 3 years old.\u003c\/p\u003e","brand":"TIDALJAM","offers":[{"title":"Default Title","offer_id":58075965554991,"sku":null,"price":24.61,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/4478\/7503\/files\/tidaljam-32-pack-invisible-ink-pens-with-uv-light-8-colors-secret-message-writing-detective-party-favors-for-kids-1.jpg?v=1781526230","url":"https:\/\/toysforkid.co.uk\/products\/tidaljam-32-pack-invisible-ink-pens-with-uv-light-8-colors-secret-message-writing-detective-party-favors-for-kids","provider":"Toys For Kid","version":"1.0","type":"link"}
