U Konserve 30oz square


Our trusted stainless steel square containers now come with plastic-free, clear-as-glass silicone lids! Perfect waste-free solution for kids lunches, picnics, travel, outdoor adventures and bulk shopping. Pack snacks, lunches and main meals while reducing single-use packaging. Our square containers are also ideal for kitchen organization, pantry makeovers, meal prep and family leftovers. Our sizes are versatile enough for all food-storage needs at home and on the go, while saving trash from our ever-growing landfills. Flexible silicone lids are easy for little hands to open, and the leak-proof feature keeps spills at bay. Our new non-toxic stainless steel and silicone combination make these lunchboxes the best zero-waste solution for you and the planet


What started as a resource for school children quickly became a full line of zero-waste food-storage essentials for the whole family to use at home and on the go. After more than a decade of growth and transition, the same goals still guide the company today. As a Certified B Corporation, the company is using business for good by creating a positive impact for employees, communities and the environment. The initial mission to protect the planet has grown into a lifestyle of reusing more, wasting less, and raising awareness about the exciting and growing movement to reduce single-use plastic. U-Konserve merged last year with EcoVessel and gives 1% for the Planet for all its proceeds.
