The classic model for professional 1" screwdrivers. It is installed in many of the company's 43 series, etc., and it is a driver that is easy to balance even when combined with various woofers and tweeters. You can see a feeling of use such as appearance, dullness, small scratches, etc. (Kobayashi Hitoshi)
