How it works
Draw it. Charge it. Watch it glow.
1. Draw
Slide a piece of cardboard inside, lay the sweatshirt flat and draw anything: a tree, snowflakes, a name, a family joke.

2. Dry & lock it in
Let it dry for 24 hours, then iron the back of the design for a few minutes. That sets it so it lasts through washing.

3. Lights off
Hold it under a lamp or daylight for a few minutes, then turn off the lights. Recharge it with light any time.

Made to last
Lock it in. Wash it. Wear it again.
🔥 Set your design (about 5 minutes)
- Let it dry for 24 hours. Leave the sweatshirt flat with the cardboard still inside.
- Iron the back of the design. Turn the sweatshirt inside out and iron over the drawing for 3–5 minutes on the cotton setting, no steam, keeping the iron moving.
- Wait another 24 hours before the first wash. Now it’s set.
🛡️ Safe for family crafting
- 💡Charged by light. The glow comes from a pigment that soaks up ordinary light. No batteries, no wires, no electronics.
- ✅Nothing radioactive. Modern glow pigments don’t use the radioactive materials of old glow paint.
- 👨👧Kids draw, grown-ups iron. Younger children should draw with an adult nearby and keep markers away from mouths and eyes, like any marker.
Straight answers
How the glow works
Daylight or a lamp charges the glow ink. No batteries, no wires.
Brightest right after charging, then it slowly fades. Charge it again any time.
The glow stands out most on black, navy and other dark sweatshirts. Thicker lines glow brighter.
Questions
Do I need a UV lamp?
Do I need a UV lamp?
No. These are glow-in-the-dark markers. They charge from normal light (a lamp or daylight) and glow on their own in the dark.
How long does it glow?
How long does it glow?
It’s brightest right after charging and fades gradually. Put it under a lamp again to recharge it as often as you like.
Will the drawing wash off?
Will the drawing wash off?
Not if you set it with heat. Let it dry for 24 hours, iron the back of the design for 3–5 minutes (cotton setting, no steam), wait another 24 hours, then wash inside out on cold. Like any print, the colours and glow soften slowly over many washes, so gentle washing keeps it looking new longer.
Is it safe?
Is it safe?
The markers use non-toxic ink, and the glow comes from a pigment that charges with ordinary light. There are no batteries, no wires and nothing radioactive. Younger children should draw with an adult nearby and, like any marker, keep it away from mouths and eyes. The ironing step is a job for a grown-up.
