Angry Birds merchandise is popping up everywhere including my eBay store. I now have in stock Angry Birds swim trunks for boys. They range in size from small (6/7), medium (8), large (10/12), and XL (14/16). Currently there are three different designs listed but one more will be added soon. They vary in color from green to blue to black. They are made of polyester and have a drawstring elastic waistband and mesh liner. If your boy loves Angry birds he will love wearing these to the pool this summer!
