The internal part of the tip of the finger allows the nail to be set in a whole spectrum of diverse depths and lengths.
The placement in different depths simulates the many different ways nails are found in a fingertip.
The adjustment of the length allows for work with diverse size of nails.
The fingers of the Habbill fold exactly as the fingers of a human hand.
To retrieve work once finished, remove the finger tip and then remove the finished nail.
