33 Back-to-School Supplies We Love

StenLock containers are made of high quality food grade stainless steel, which resists bacteria and odours better than plastic—so there's no lingering scents and discolouration. We love the airtight seal on these lightweight containers—which, in addition to keeping food fresher, longer, means they're totally leak proof. We haven't had one accident yet, and we toss ours into backpacks and bags willy nilly. One even survived a tumble down the stairs…lunch intact!
