There’s a size for every task. They’re not just for storing food – There’s no doubt these stylish kitchen accessories are great for food storage, but their usefulness doesn’t stop there. They make great mixing bowls when you’re whipping together something delicious in the kitchen too! Storing food in glass is the only way to go – One of the biggest benefits of storing foods and liquids in glass is that it’s nonporous. You won’t have to worry about food, germs, or even smells seeping into your glass bowls. The same can’t be said for plastic! Sleek, earth-friendly bamboo lids – Every set of small glass containers comes with (4) eco-friendly, bamboo wood lids that form an airtight seal around the bowls. There’s not a hint of plastic on these rectangle kitchen storage containers. Unlike plastic, these will last you a lifetime – Plastic will eventually crack, snap, warp, or wear down. These glass food saver containers won’t! They’re made from heat-resistant, super-tough borosilicate glass that’s safe for the dishwasher, microwave, freezer, and fridge.
