If you're thinking about portion control and need a compact design to fit in your bag, this black+blum lunch box fits the bill.
It's inspired by the brand's first steel lunch box and is made of durable stainless steel, so it's oven-safe for heating up food and freezer-safe for storing pre-cooked food. It's leak-proof with the silicone valve creating a secure vacuum-sealed closure. The silicone band holds a handy stainless steel fork in place.
This lunch box is part of a range from black+blum inspired by vintage army and camping accessories, updated with a minimalist design in stainless steel that ages beautifully.
