We always do boxes for boys because the coordinator at our church said that every year about 80 percent of the boxes dropped off are for girls

Boys are fun to shop for too!
For boys (5 and over) we put in things like a solar calculator and some school supplies (basics like pencils and sharpener but also some cool looking pens and colored pencils and notepads), sunglasses, yo-yo, silly putty, hackey sacks, beach balls, mini magnadoodle, dental hygiene stuff, washcloth.
We remove some items from their packaging so we can fit more in the boxes.
