Forestone - FBB025 Clarinet Reed French F2.5 - Brown Forestone reeds for all saxophones and clarinets come in 1/2 strengths from 1 - 5. They have the functional properties of cane but are consistent, do not degrade with use, and are not subject to fluctuations in temperature, humidity, altitude or other factors. Forestone reeds are made from a special composite material: a mixture of polypropylene resin and cellulose wood fiber, more than 50 percent of which is bamboo. This material is odorless, non-toxic, and recyclable, and when formed into a single reed, possesses exceptional sound, resilience, and flexibility. French cut
