Joycover 28-Pack Invisible Ink Pens with UV Light - Spy Gadgets for Kids Party Favors

The Joycover Invisible Ink Pen set includes 28 pens in 7 colors, each with a UV light that reveals hidden messages. Designed for kids ages 3 and up, these non-toxic, washable pens work on paper, cloth, walls, and skin, making them a versatile addition to spy games, party favors, and classroom activities.

How does the invisible ink work?

Each pen writes with an invisible ink that is only visible under the purple UV light built into the pen cap. Kids can write secret messages or draw invisible pictures, then switch on the UV light to reveal them. The effect works on most surfaces, including paper, skin, and walls.

What's included in the 28-pack?

You get 28 pens: 4 each of 7 colors (blue, black, red, pink, yellow, green, and purple). This is enough for a whole classroom or party goodie bag. Each pen has a UV light at the top, so every single pen can write and reveal messages.

Are these pens safe for children?

The ink is non-toxic and flavorless, making it safe for kids ages 3 and up. It is permanent on surfaces but washable from skin and most fabrics with soap and water. The pen bodies are made of durable plastic. As with any small parts, adult supervision is recommended for younger children.
