Colour-In Rainbow T-Shirt


Who doesn’t love a rainbow design? These t-shirts are soooo fun to colour-in but also symbolise hope.

The Jex colour-in t-shirts are 100% cotton, have short sleeves and not only come with a rainbow selection of fabric pens but also one our key rings. They are packaged in a box that is just the right size to fit through a letter box so need to wait around for the postie.

To colour-in Jex rainbows there’s no need to remember a fancy rhyme about York and battles, just unleash creativity and let the colours flow. Let’s see who sticks to tradition and who goes wild with the patterns or maybe monochrome? There’s no right or wrong, except for it being fun…that is most definitely right!

All designed, printed and packed in Suffolk, England.



It couldn’t be simpler to get started enjoying this colour-in t-shirt but have a quick read of this before the fun begins.  

Step 1: Check the garment fits before colouring it in. Once started, you can’t return it.

Step 2: Use the box to protect the work area, the pens are permanent

Step 3: Colour-in the top! Just try and stay in the lines! 

Step 4: The t-shirt should be touch-dry within 20 – 30 minutes but leave it for a minimum of 12 hours. Keep it away from other clothing and upholstery for this time or until completely dry to avoid the ink marking.
