I spied one of my friends holding this lunchbox for her son today and it was love at first sight. The cover is of coated linen, they are PVC-free, phthalate-free, and lead safe, they have a detachable long strap for wearing as messenger bag or backpack, and an adjustable carrying handle allows lunch box to be secured to another bag or hung from a stroller. What more could you want? There is a choice of 6 different designs with these simple and charming graphics. They are available on Soyoungmother.com along with their other products such as cooler bags and diaper bags.
