The Black+Blum Meal Prep Boxes are ideal for anyone who loves meal prepping or eating on-the-go. Crafted from premium 18/8 stainless steel, they’re durable, lightweight, and microwave-safe. The airtight and vacuum-sealed lid is 100% leak-proof, helping keep food fresh longer, and the innovative lid lock vent lets you microwave without the splattering—no need for cling film. The lid is also semi-transparent, making it easy to see your meals, while the removable seals make cleaning a breeze.
Make the switch to a more sustainable way of storing and reheating meals with these functional containers.
Every Black+Blum purchase contributes to positive change. As part of the 1% for the Planet initiative, the brand donates 1% of every sale to organisations tackling food waste. These efforts support over 375 community partners, including food banks and soup kitchens, redistributing meals to those in need while reducing greenhouse gas emissions from landfill waste. Plus, their innovative products also help reduce food waste at home, making meal-prepping and storing leftovers more sustainable and convenient.
