Version française Chinese version Vandoren Authentication Site Like every world-renowned quality product, we are the victims of counterfeit. We have therefore devised a system of identification for each of our reeds, each of our reed boxes and each of our mouthpieces with the help of an individual code: The reed box has a code in the form of XXX-XXX-XXX printed on the cellophane above the bar code. Inside the box, every reed carries a marking in the form of XXXXX-XXXX engraved on the table, above the Vandoren label. Every mouthpiece has a code in the form of XXXX-XXX * Verify the authenticity of your reeds here Verify the authenticity of your mouthpieces here
