Made from durable borosilicate glass with BPA-free, LFGB-certified silicone lids for reliable everyday use. Why choose borosilicate glass? Borosilicate glass is designed to be more durable and resistant to temperature changes than standard glass, making it a practical choice for everyday food storage. It’s less likely to crack from moving between cold and warm environments and is built to handle repeated use over time. Unlike plastic containers, glass won’t absorb stains or odors and helps keep food tasting fresh. It’s also made without BPA, making it a long-lasting, reusable option for a lower-waste kitchen.
PlanetBox began in 2009 with parents Robert and Caroline Miros, who shared a vision for a more sustainable lunchbox . They were frustrated with the lack of plastic-free lunchboxes on the market, and sought to create a stainless steel option, designed to be long-lasting, durable, and zero-waste. They wanted their kids to be able to get the nutritious foods they needed, all while reducing the waste that typically comes along with it.
Take good care of it and there's no reason it won't last!
