These clip-on supports are designed to be a comfortable place for your finger or thumb to hold your flute more securely. Instead of bending your hand to keep the flute stable, they support your thumb or finger at a much more comfortable angle. Made of plastic, they just snap on and off quite easily.
The cheapest of these clip-on supports can be bought for less than $10 each at Amazon.
A more expensive style, known as the Thumbport, costs around $20. Constructed with both hard and soft plastic, it is designed not to scratch the flute nor to slip when in use (both of which problems do exist with the cheaper version).There is also a Pinkieport to support the little finger, also priced at $20. Both are available directly from Thumbport.com.
