Packing food for on the go is always a little risky — one poorly sealed container, and you've got a gigantic mess at the bottom of your lunch box. Turns out, the secret to traveling with snacks, leftovers and even toiletries sans spill comes in the form of Stasher reusable silicone storage bags — all for under $15.

Stacked with thousands of online reviews from parents and teachers, alike, Amazon shoppers rave about the food storage containers from the woman-founded brand. "There is no end to what these can be used for. Really great for travel." says one Amazon reviewer. The reusable lunch bags are a more eco-friendly option than single-use plastic bags.

Whether you need it to keep something hot, cold or room temperature, a single bag can be used over and over (up to 3,000 times or more than eight years of daily use, per Stasher). That's not all there is to love: It comes in eight colors and 14 different sizes like pocket, sandwich, bowl and stand-up shapes — perfect for your lunch-packing, leftover-saving and sous-vide-cooking needs.

Our culinary pros at the Good Housekeeping Institute are big fans, too. During home testing, we found that they kept herbs wrapped in a damp paper towel fresh for weeks, and they take up minimal space in the fridge, so no need to play Tetris with other food items.

Some online reviews noted difficulty with washing. To remove any food remnants — whether sticky, smelly or a mix of the two — simply pop them in the dishwasher, and they'll be good as new. Stashers are also safe in the freezer, microwave and even withstand boiling water.

It may seem like a big investment at first, but it pays for itself over time. Instead of picking up a box of plastic baggies every time you go to the grocery store, you'll already have a permanent collection of silicone bags stashed and ready to go.
