The Black+Blum Meal Prep Box is ideal for anyone who loves meal prepping or eating on-the-go. Made from premium 18/8 stainless steel, this single container is lightweight, durable, and microwave-safe. The airtight, vacuum-sealed lid ensures your food stays fresh for longer, while the innovative lid lock vent allows microwaving without splattering—no cling film needed. The semi-transparent lid makes it easy to see your meals, and the removable seals make for quick, hassle-free cleaning.
This container is microwave, dishwasher, and oven-safe (lid excluded) and is designed for easy cleaning and convenient storage. It nests with other sizes or stacks with same-sized boxes to save space.
Make the switch to a more sustainable way of storing and reheating meals with this functional container.
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.
Founded by Dan Black and Martin Blum over 20 years ago, Black+Blum is a UK-based brand known for innovative, eco-conscious food containers, drinkware, and accessories. Designed with reuse and sustainability in mind, each product is thoughtfully crafted in-house using durable, eco-friendly materials where possible.
