VERSATILE: Made up of 2 containers with separate compartments and 2 without, the multifunctional 4 piece glass container set from Navaris is ideal for packed lunches and portion control on the go as well as kitchen storage and food prep at home. GLASS CONTAINERS: The 600 ml and 1 litre containers are made of borosilicate glass, so they're food-safe, taste-free and hygienic. The silicone-sealed lids are airtight and leakproof to keep food fresh. HEAT RESISTANT: With the lids removed, the glass containers are heat-resistant and oven-safe up to 250°C, so they're great for baking, heating and serving up oven dishes such as gratins, pies and bakes. MICROWAVEABLE: Thanks to built-in steam vents in the lids, the leakproof food boxes are suitable for use in the microwave. The versatile containers are also dishwasher-safe and freezer-safe. STACKABLE: Stack the rectangular tubs one on top of the other for neat and tidy kitchen storage or easy meal organisation in the fridge or freezer.
