Tackle boxes vary and this is a system which includes a selection of boxes. Each box has a black base which is split into compartments and a transparent lid so that it is easy to see what is inside. There is a large box which is 27 x 18.5 x 6cm and it has nine different compartments of different sizes. Then there are four smaller boxes which each have different sized compartments. The boxes are light and can easily fit in a tackle bag. The dividers can also be removed if you want some more space in the boxes.
