These are inserts to subdivide the bigger variant of drawers that come in Stanley small parts cabinets available in Germany.

There are three variants:

• Quarter Insert: Takes up one quarter of the drawer. Use two stacks of two inserts to subdivide one drawer into four compartments
• Half Insert Shallow: Takes up the bottom or top half of a drawer. Stack two, or combine with two Quarter Inserts to fill a drawer.
• Half Insert Tall: Takes up the front or back half of a drawer. The other half can be filled with another Half Insert Tall, or by two Quarter Inserts in a stack.
