In one aspect, a storage device including a container has a first side wall, a second side wall, a bottom wall, and an indentation. The first and second side walls each have a pair of guide members forming a guide track. The storage device further includes a divider having a first end, a second end, a wall extending along a plane between the first and second ends, and a bump. The first and second ends each have a flange extending substantially perpendicular to the wall of the divider sized so as to fit within a corresponding one of the guide tracks. The divider is removeably insertable within the container such that the bump of the divider extends into the indentation of the container.
