Langstroth frames into flow hive 2

Can I use Langstroth frames in a flow hive 2 or just keep the ones that come with the hive and add my brood box to it?

I have 2 X Flow 1. but are very near identical to 2. I am assuming the question is “can I use any lang frames in my Flow brood box.” The answer is yes, if they conform to the Australian lang hive measurements. But as you get the frames with the brood box ,why not just use them?

Hi there. I purchased langstrop frames with wax foundation for my brood box in my flow hive 2 with no issues at all. The langsthrop frames from the nuc went straight in as well.
