Here is the description from Mike's website:
MF3
Rim: 7.76mm * Cup: 33mm * Throat: 8.43mm
My most popular design, the MF3 boasts a large inside diameter and a deep, funnel-shaped cup. The comfortable, slightly rounded rim allows for excellent flexibility and ease of articulation. The depth and shape of the cup allow you to put a lot of air through the instrument, providing an expansive low register, and a rich, mellow tone.
PRICE: $105 (includes shipping)
