Alto saxophone reeds, size 1, pack of 10. - Brand: Vandoren - Model: SAXOPHONE ALTO Mib - Eb - Quantity: 10 reeds - Size: 1 These are very rare. I purchased them for 5,500 yen per box. Regarding the thickness of saxophone reeds: - Beginners usually use "2 1/2" - As you improve, you move to "3 1/2" ...or so it goes. After much trial and error, I've found that thinner reeds produce better sound quality. And, you can use all the reeds in the box. It's economical and environmentally friendly, a great deal! Thank you for looking.
