Specification Brand : Generic BulletPoint1 : Embouchure Visualizer for Trombone – Rim diameter: 0.98" (25.0mm), Size: 1.57" × 3.31" (40mm × 84mm), Material: UV-cured resin. Note: Specs may change without notice for product improvement. BulletPoint2 : The BRASS DESIGN Embouchure Visualizer is now newly updated! With improvements to the material, coating, and overall design, it is now more user-friendly and highly durable. BulletPoint3 : The visualizer is a practice tool that allows you to check your embouchure and lip movement. You can observe your own embouchure, which is usually difficult to see. Furthermore, it can be attached to your instrument and used in a real playing posture. BulletPoint4 : You can also attach it to your instrument. Your posture, field of vision, and finger position can greatly affect your breath control, embouchure, and overall playing feel. Practicing with the visualizer attached to your actual instrument provides greater training benefits than buzzing with the visualizer alone. [Note] It is not intended for playing as a mouthpiece. BulletPoint5 : Designed to look as if it were cut directly from a real mouthpiece, the BRASS DESIGN Embouchure Visualizer also focuses on aesthetic appeal. The shape was traced from an actual mouthpiece and digitally sculpted using 3D software to achieve this design. BulletPoint6 : Note: Due to the nature of 3D printing, small marks, bubbles, or slight discoloration may be visible. These do not affect the product’s quality. Please handle with care, as dropping or applying strong force may cause cracks or breakage.
