I found the perfect solution to store my cutters.
You can combine as many of them above and next to each other and the 24x 60x23x20mm compartments fit my largest cutters very well.
Most such boxes have compartments way too wide or twice the length of the cutters, thus wasting a lot of space and only offering 6 or 12 compartments. Most also are boxes that open to the top or cannot be combined to expand the selection.
