Black+Blum Mattermos 400 ml FAQ

Question 1

How long will the Mattermos keep food hot or cold?

Accepted Answer

The vacuum sealed flask keeps food warm for up to 6 hours and cold for up to 8 hours. This makes it suitable for packed lunches, soups, or chilled snacks taken on the go. The 400 ml capacity is designed for a single serving.

Question 2

What is the flask made from and does food touch plastic?

Accepted Answer

The flask body is made from stainless steel and nylon, and the lid now has a stainless steel underside so food never comes into contact with plastic. The included spoon contains wood fibre from sustainable sources. All materials are BPA free and comply with food safety regulations including EC 1935/2004 and 2020/1245.

Question 3

How should I clean the Mattermos flask and spoon?

Accepted Answer

The flask should be hand washed only to protect its vacuum seal and finish. The spoon, however, is dishwasher safe for easy cleaning. Each unit arrives packaged in a gift box, ready for branding and presentation.
