This box is great for long, skinny items but is an equal opportunity box and will hold other things too.
You will need:
-one slice of square paper
Fold the paper in half the triangle way then unfold.
Fold in half the other triangle way and unfold.
Fold the paper in half the normal way then unfold.
Collapse the paper to look like the last picture.
Fold the triangle in half from the right corner. Looking at the last picture might help to better understand.
Fold the top right corner so the point lines up with the crease.
Fold the top left corner down to meet the corner of the last fold.
Tuck the left side into the right side pocket.
Flip the model over and repeat Step 4 on this side.
Fold the bottom triangle back and forth a few times, this makes it easier to open the box and gives it a nice crisp crease.
Open up the box and fill with desired fillings.
