MDD
Mmd Vivian







The MMD Vivian differs from the MMD Princess: it uses a modified, strengthened UPE stem that keeps UPE's thocky, smooth sound while resisting breakage. The top housing is PA12, and the bottom housing uses a modified PUM material, which testing suggests produces a deep, clacky sound.
