Introducing "Zatsunei-shi," a dedicated item designed to suppress unwanted vibrations and noise. It absorbs subtle noise, clarifying the contours of the sound. Enhances the purity of the sound, supporting concentration during performance. Black is a standard color that blends in, while white offers a clean feel and complements bright costumes and stages. This is a "Zatsunei-shi" featuring a white butterfly with delicate embroidery. You can adjust the sound by using it with your own felt placed under the butterfly. One white felt sheet is included.
