Toca 3900D Traditional Series Bongos - Dark WalnutToca is committed to being green and environmentally friendly. The wood we use is harvested from a plantation in Thailand, where our drums are then lathed and handcrafted by local musicians. This carefully managed resource is much easier on the environment than wood taken from primary forests. These drums combine a contemporary finish with the essence of Afro Cuban tradition, all with notable old school design. 7 & 8 1 2 Heads Two ply Ash oak shells
