If you're into Lifefactory's BPA-free glass bottles, you're going to flip for these tempered glass food storage containers ($15 to $20). I love that they offer three different sizes to suit my snack or lunchtime needs — one-cup, two-cup, or four-cup sizes, with their signature silicone sleeve for nonslip grip and protection. The silicone button tabs keep the lids secure, and these babies are dishwasher-, oven-, microwave-, and freezer-safe! And because they're glass, they're durable and stain-resistant, and I love that I can see what foods are in them. They come in the four fun colors shown, and although I found them to be slightly weightier than plastic or stainless-steel containers, I love how easy they are to eat out of and clean.
