This product is a **bamboo pinkillo (Pinquillo)** purchased in Bolivia, South America. It is a vertical flute-type folk instrument traditionally played in the Andes region. Although it is a new, unused item, it is handmade using natural bamboo material, so there may be color unevenness, small scratches, and individual differences characteristic of the material. Also, you may see natural color variations and dark spots on the inside and surface of the tube, but this is due to the nature of bamboo and is not a defect or stain. This instrument is widely recommended, from folk music beginners to those interested in Andean music. *Please note that this product is not for those seeking a perfect condition like an industrial product. It is suitable for those who understand the characteristics of South American-made, natural material instruments. Feel free to comment if you have any questions or would like additional photos.
