The Thumbport Thumb Rest allows greater balance in holding the flute. It is comprised of a C-shaped shell and a thumb-like extension.

The Thumb Rest helps the player to place the right thumb at an efficient spot and provides additional support. It reduces strain and stress on the hands. 

The Thumbport II has a lower default angle for the thumb. It's a little thicker and more rigid. It has less contact with the flute. And, its extension arm is a little shorter (when attached to the flute, it may go into the case easier for some). Also the end of the extension has a more rounded shape. If the default angle on the Thumbport II (when the back top end pushes against the flute rib) is too low, one can use a blade to cut off the end a little. The angle can be modified in this manner. Adding isn't as easy as removing; that is the reason why the new shell is longer.

Simple to clip-on and doesn't scratch or otherwise damage the finish of the instrument.

Available in four different colours.
