Bowls: borosilicate glass
Lids: 100% silicone
100% recyclable borosilicate glass, 2 to 3 times stronger than normal glass!
The advantage of using borosilicate glass is twofold. As well as being endlessly recyclable, it is also long-lasting due to its resistance to high temperatures (around 300°C) and thermal shock. As well as being an eco-friendly and durable material, glass is ideal for storing food as it retains flavour.
You can therefore use it in the freezer, microwave, oven, bottle warmer and bain-marie (or any other appliance that steam heats). Really practical, the Isy Bowls are also dishwasher-safe and can be sterilised. No leakage possible with their hermetic silicone lids. What's more, they do not stain when they come into contact with food (such as carrot or tomato).
