Our calabash deze is made of strong and durable fiberglass and is designed for the amplification of mbira and kalimba nyunga nyunga instruments. This fibreglass calabash is ideal for travelling and heavy duty usage. It is a good alternative for the traditional natural gourd because it is not as fragile. A stick is used to hold the mbira/kalimba in place. On the fiberglass gourd are bottle top buzzers, they are removable. Fiberglass calabash only, mbira instrument and stick are not included.
