A:
My case came with one long removable divider that divides the case in half lengthwise. It also has eight smaller dividers that can be positioned for different sized compartments.
This gives a maximum of ten adjustable compartments. The case is also equipped with two small pockets on the inside of one end of the case for very small items. I placed the parts lists and paper work that came with my reels in these pockets.
I am not a fly fisherman. I do have one fly reel that I never use. I could easily place ten reels of the size of my fly reels in my case with padded partitions between each reel to protect it. This would leave room to place other items such as line in the case next to the reels.
