We love this hugely successful range of T Shirts and so we have expanded the range to include this new Lion Design. A unique interactive glow t-shirt for children; Using the included Glow Torch or a mobile phone torch you can create your own designs on the clothing - again and again - kids love it - Makes the perfect gift! The glow effect lasts between 5-10 minutes, before fading away completely. This means you can keep interacting with the t-shirt throughout your day or night. The T-shirts are machine washable, perfect for when you come back from a festival or a children\'s party. As they are 100% cotton, they feel great to wear due to the natural fibres. Each T-shirt includes a Glow Torch on a lanyard, allowing you to charge up the glow canvas. You can also create cool shadow effects from a distance. As seen on BBC\'s Dragons\' Den 100% Cotton. The T-shirts are fully machine washable following the care label. CHILDREN\'S Size Guide (Age) 3-4 Yrs Europe (CM) 104 Chest (inches) 24/26
