Flex container

I have a row of icons and as there are 4, I never want it to have 3 on one row and 1 on the other.

Is there a way to achieve this in a flex layout (all those controls are confusing and dont seem to work for me) or would I be better putting two lots of containers containing 2 columns?

This is a desktop width
