We know that making the music box movement become a DIY module for people to design their own boxes will attract many makers. However, at this early stage, we try to control its performance and stability first for building product's reputation, so we cannot allow customers to purchase the mechanical part alone. Any mistake in assembling the box may interfere its music playing performance and even damage its hardware. To avoid potential negative feedback due to inappropriate assembling process, we cannot sell Muro Box without its wooden case. However, after our product is mature enough for developing a DIY module, we will definitely share this news with our fans.
