This is a synthetic reed (resin reed) for Yamaha alto saxophones. It has a strength of 2 1/2 and offers a light playing feel. I am selling it because it didn't work well with the mouthpiece I use. I've only used it a few times for testing, so it's in good condition. It will be shipped after being disinfected with alcohol. Please understand that this is a used item, and purchase it only if you are satisfied with the condition. - Brand: Yamaha - Model: Synthetic Reed for Alto Saxophone - Size: 2 1/2 - Material: Synthetic material
