is 1/16" (1.59mm).

All of our saxophone key felts are die cut from the finest
grade of felt available, woven from 100% wool. Unlike felt that is woven using a
blend of wool and synthetics (such as rayon), felt made from 100% wool is more
dense. Density is an important factor in a saxophone felt because of the
necessity for maintaining proper key adjustment. Less dense grades of felt
are spongy and easily compress after a short time, which means keys can go out
of adjustment soon after leaving the shop. Technicians will also find that
unlike synthetic blends that shred and tear, 100% wool felt is easier to cut and
trim.

Storage case is made of tough, clear, abrasion
resistant, K-resin high strength copolymer. Sturdy design with hinged top that
overlaps side edges to keep out dirt and protect contents. Permanent labels
provide quick easy size identification.
