This Stanley Sortmaster Junior Organiser contains 8 removable dividers that allow you to customise the box to suit your needs. This organiser has a unique 90-degree angle in the main compartment design, allowing for storage of hammers and angled tools, as well as a special lid structure where the upper lid interlocks with dividers and prevents movement of small parts from one compartment to another. It's stacking option allows secured stacking of several organizers to save space and maintain organization.
