Thank you for viewing! This is a wooden frame drum, with both the striking surface and shell made of wood. The shell has 83 jingles attached. The subtle sizzle sound is produced by the vibrations when struck. The sound is similar to a cajon or conga. It has no sustain, but it's simple, well-contained, and records well with a microphone. Although the volume isn't very loud, it's ideal for the base rhythm of an acoustic sound. Striking surface: Approximately 20 inches (about 50 cm) in diameter, made of wood. Shell: 8 cm deep, made of wood. 83 jingles Shipping is included in the price. Thank you for your understanding of the price!
