Flame Boss currently does not offer a storage case, but we have numerous users who prefer using the Condition 1 case. Check out their website at https://condition1.com/.
The case that fits all the components in our FB500 controller kit is the Condition 1 14" Medium Travel and Storage Case #075. Here is the link to that product: https://condition1.com/collections/c1-carrying-cases/products/condition-1-case-075
