All Hodge silk swabs are made from 100% silk. Silk is very absorbent, soaking up water in instruments better than any other natural material on the market, including both cotton and chamois.  Most uniquely, silk is also very compressible, making it possible to pull through instruments with large variations in bore size.  In addition, silk is lint free.

The silk alto clarinet swabs are made with a large plastic coated weight allowing the swab to drop through the instrument without hanging up in the large key holes. They are capable of cleaning the entire instrument including the neck and mouthpiece without taking the instrument apart.
