What does everyone use to store all their bits and tools for bit fitting?

Hello. I've finished the first Module. Thank you for the information especially relating to OTT injuries of the mouth. I hope to learn more about how injuries could impact bit fitting. What are the resources (in module 1 a 'call' was referenced to), assessment criteria and other processes to complete the course? I thought I might get extra information about this in an email after purchasing so I wanted lots of details and clarification to get myself organised 😊
