Promotional Black+Blum Mealprep Box 3pcs Set Small, Medium This set of three microwavable stainless steel meal prep boxes is designed for everyday use—lightweight, durable, and airtight. Whether for breakfast, lunch, or snacks, they’re ideal for food storage, on-the-go lunches, or oven-to-table meals. Each container features an innovative microwave-safe steel construction, with a vacuum-sealed, leak-proof lid that keeps food fresher for longer. The semi-transparent lid lets you see what’s inside at a glance, while the high-quality stainless steel base is dishwasher-, freezer-, and oven-safe (lid not oven-safe). The removable seals make cleaning effortless. The unique lid-lock vent allows you to microwave your food without removing the lid, reducing heat-up time and preventing splatter. Designed to nest for compact storage or stack when using the same size, these BPA-free containers offer smart functionality for every meal.
