If you have lots of small items that you use for fishing, then it is well worth having a useful box to keep them in. This is actually a three-pack of transparent plastic boxes which can be used to organise them as they have different sections In them. The boxes have 18 square sections in them and they measure 27.51 x 17.98 x 4.15 cm. The dividers can be adjusted so you are able to accommodate all sorts of different items of varying sizes. The box will fit into a standard-sized tackle bag. It is see-through so it is easy to reach for the right box and select the item that you need.
