Our materials

Strong, durable and lightweight

Why does reusable plastic meet our commitments?

Quite simply because its light weight makes you want to take your bento boxes and bottles everywhere with you! What’s more :

- Even though we have made sure that our products are recyclable, they are so resistant that they require little recycling! 

- Our bento boxes (except the MB Element, MB Capsule and MB Gram) are microwave and dishwasher safe! 

- Our products are guaranteed BPA-free (in accordance with the regulations). They also comply with international food standards.

- The transport and manufacture of reusable plastic products are less energy-intensive and generate less CO2 emissions than glass products (which are a lot heavier).
