To ensure the box is locked & sealed properly, check that the edges of the base and silicone seal on the lid are clean and dry. Firmly push the lid down on all sides and then press the valve down. Secure the box with the silicone strap.To open the box/release the vacuum, pull the valve upwards. Then separate the lid from the box by pulling at a corner/short side. Please be careful when the box contains liquids.
Review from BBC Good Food 2020:
'This lunchbox is really cleverly designed. It's stainless steel, with a brightly coloured silicone strap (we had an orange one, but it also comes in blue or green). The strap also holds a stainless steel fork on the outside of the box. There's a removable divider that slides up and down to make two compartments of whatever size you fancy. Unusually, you can put the base section in the oven. It's also safe to use in the freezer, so when not pressed into service as a lunchbox, it can be used for freezer meals. However, it's not microwaveable, and is only partially dishwasher-safe (the lid and strap should be handwashed). The box is lovely to look at and despite having no clips, is leakproof. It seals with a valve that you open and close. We packed a salad and liberally drizzled olive oil over it before turning the lunchbox upside down and swinging it about a bit, but it didn’t leak a drop. We also checked to see if it was big enough for a sandwich. It needed to be cut in half, but the box was tall enough for the sandwich halves to be stacked on top of each other. There was room for a small salad too.
Made from high quality stainless steel, this nifty lunch box also comes with a silicone strap, a stainless steel fork which tucks into the silicone band, and a removable divider to separate foods. It holds together tightly – the most secure out of all of the lunch boxes we tested – thanks to a vacuum release valve system, which is nifty, and ensures no leakages. While it was tricky to choose between this lunch box and Black + Blum’s sandwich box (which has a bamboo lid which doubles up as a chopping board), this one came out top as it has the added bonus of being able to be used in the oven, and can also be placed in the freezer (obviously not suitable for microwave as stainless steel. Box, fork and divider are all dishwasher safe. It’s surprisingly lightweight, and also looks fantastic! '
