Blood sandalwood (blood purple sandalwood) is a high-density wood primarily originating from Africa, possessing a unique charm distinct from rosewood. Its core wood has a deep red color, like blood, which beautifully darkens with age. It is extremely dense and hard, resistant to humidity and climate changes. It has high vibration transmission, resulting in a rich resonance due to its high density. It has depth and thickness in the mid-low range, and the high range is smooth and delicate. ※These are very easy-to-use koma (bridges), and I've been using them frequently as of late. Size: 15mm x 12mm x 9mm There are slight individual differences due to handcrafting.
