This high-quality wooden pen holder is a traditional hourglass shape, which perfectly fits the curve of the index finger. Aside from being comfortable, this shape will help develop the proper pen grip for cursive handwriting. The nib is held by a traditional metal 4-prong clamp, which is very effective and works with most nibs (including G-pens and our French nibs). It takes a bit of finesse to insert the nib; if it's difficult to push in, try "rocking" it back and forth while it pushing down. Be sure to hold the nib by the base and not the point and be careful to not poke yourself. Below is a Youtube video that shows how to insert the nib. It's actually not difficult, just takes a bit of practice.
