Storage box for 10 NERF darts.

The box can be used both for stowing darts at home and as a “spare magazine” for on the go.

The box is loaded from the top—and darts can be removed from the bottom. The upper edge is thickened to prevent the darts from falling out.

Darts from third-party manufacturers often vary only slightly in length and diameter; I’ve tried to strike a balance that accommodates as many darts as possible.
