High quality: Our trumpet mouthpieces are made of brass, offering a comfortable touch and excellent sound. The thick silver-plated surface is easy to wipe and maintain. Value Pack: The package includes 3 trumpet mouthpieces (1x 7C, 1x 5C, 1x 3C). This set meets various performance and practice needs. Precise Size: The trumpet mouthpieces come in three sizes, ranging from small to large, with consistent design in the outer rim, inner cup, inner diameter, and backbore. The engraved markings allow for quick identification of each type. For beginners, the 7C is recommended as it is easier to produce sound. As lip strength improves with practice, players may progress to the 5C and then the 3C, which is commonly used by professional trumpet players. Application: These mouthpieces are compatible with most standard trumpets and suitable for use in schools, concert halls, bars, homes, and band practice areas.
