The BG A30A is a round-shape pull-through swab designed to match the alto saxophone's bore. It combines microfiber and bamboo silk with a retractable foam core that expands inside the body to make full contact with the interior walls. Two metal weights on the cord guide it through the instrument smoothly, and the high-absorbency materials pull moisture out quickly and completely.

This round-shape design outperforms flat swabs because it actually fills the bore instead of just passing through the center. Lint-free, chemical-free, machine washable at 30°C, and rated for over five years of use. Toss it through your alto after every session—your pads and tone holes will thank you.
