When you do well in school, you get a gold star. When you do well for the environment, you get a green one! Little Green Star's hip, funny, slogan T-shirts and onesies are made of soft 100% certified organic cotton. The designs are printed by hand and they use water-based inks, giving you style, comfort and peace of mind. Water-based inks are PVC-free and also made without petroleum-based solvents. They are safer than plastic prints and keep their colour better after multiple washings.
