Roi's Flute Master Cleaner series, which is widely supported as a flute care product, now includes a new model specially designed for alto flutes!
The washable, super-absorbent fine fabric has been retained, and a newly developed silicone rod with a flexible, bendable tip has been adopted to accommodate the head pipe of U-tube flutes. The outstanding water absorbency removes water from the tube. Try it for yourself!
