Guidelines for Writing Good Descriptions

The third loop (c) is another
U-shaped turn to the right
that starts 2 cm beyond (b)
and has a diameter just small
enough to fit snugly within
the second loop (as well as
the first).
The wire in each inner loop
touches and runs parallel to
the outer loop that wraps
around it. All three loops
lie in the same plane, and
pushing them out of that
plane just enough to slide
several sheets of paper
between them makes the paper
clip act like a spring and
squeeze the sheets together.
