Back to school shopping - the coolest lunchboxes and lunch bags.

It's a tradition for so many families - the school year starts off with a clean new lunch box, full of promise (and not so full of last year's peanut butter crud). Here are a few that we love because they're not only adorable, they're built to last. Pink Robot Lunch Box Our readers have begged us for pink robot items; leave it to Beatrix NY (at top) to have that very thing covered. ($34 at Beatrix NY)

Laptop Lunch Bento System For older kids, a bento system is so practical, especially in this season's hot purple. ($25 and up at Laptop Lunches)

Eric Carle collection lunch boxes Preschoolers heading to school for the first time will find comfort in the company of Brown Bear or that Very Hungry Caterpillar. ($18 at Pottery Barn Kids)

Built NY animal lunch bags Built NY always does nifty things with neoprene, and now, it's lunch bag animals named for downtown New York streets--Astor Owl, Cornelia Kitty, and Delancey Doggy. Maybe you should be packing hot pretzels and chocolate egg creams in there. ($20 from Built NY)

Kermit Lunchbox What more is there to say? ($13 at perpetual kid)

Rebel Green reusable lunch bags Older girls might prefer these brown bag style eco bags from Rebel Green with an earth-friendly backstory. ($24 at Kate's Caring Gifts / Use SCHOOL2011 at checkout for a 20% discount on your entire order)

Cookie Lunch Sack Give your little kids a sweet message about learning. Or is it cookies. ($28 at Dabawalla / 20% off with code CMP20)

DIY lunch bag Can't decide on a design? Let your kid make his own with this cotton eco-tote that you can color yourself with Tee Juice Fabric Markers. ($21 at Nubius Organics / 15% off with code CMP15)

Lunch Munch Anchor's Aweigh lunchbox These lunchbags have plenty of room for a big kid sized lunch and a handy clip for easy carrying. And we just can't get enough stripes!
