Free of plastic - the black + Blum stainless steel lunch box is an absolutely tight lunch box with 3-in-1 multifunctionality: lunch box - oven dish - storage container. This means that you carry your lunch in the lunch box, prepare meals in the oven or cooked dishes that can store pre-stored in a freezer. The silicone Valve creates a secure, vacuum-tight seal. The adjustable divider allows you to separate foods. The fork and the belt have been added for convenience. Thus, the perfect, plastic-free lunch box: dimensions: 17.5 x 13 x 5.5 cm. The stainless steel series is designed for sustainability and longevity. Want to protect meant for people who deliberately live and enjoy and our environment. The mantra of "One-time buy, buy well". This is what this collection drives and inspires us to expand it every year and refine. Of course, BPA-free.
