This tackle box is micro sized - it measures 4 1/8" by 2 1/2" by 1 1/4". I call it the Tanago Tackle Box. It has six compartments of various sizes. It will hold the bamboo line winders plus some micro fishing floats, some extra hooks and sinkers, and perhaps even some micro fishing flies.
It also works nicely for seiryu fishing. It will hold several sizes of split shot, hooks, and both the Acorn and top Top Floats. For keiryu fishing, it will hold split shot, hooks and a spool of yarn marker. For its size, it is really quite versatile
