Available in three versatile sizes & two colours, these steel & glass containers are perfect for meal prep, batch cooking, storing leftovers or eating lunch on-the-go. The medium size has a 1.8 litre capacity and features a durable microwave safe steel base paired with a toughened glass lid, giving you a clear view of your food. The push down tab creates an airtight vacuum seal, keeping your lunch where you want it, & your food fresher for longer. Press the lid on and then push the tab down to create the seal. To take the lid off, pull the tab up first to release the vacuum seal. Important: The vacuum seal only works when food is at room temperature or cooler. Hot food releases steam and moisture, which prevents the vacuum from forming. Let food cool before sealing to ensure it is fully leakproof. Elevate your kitchen game & keep your food fresher than ever.
