DISASSEMBLY / ASSEMBLY:
This drone flute arrives assembled in numbered pieces. Please disassemble with care if deciding to do-so for portability (slowly wiggle around the joints as you pull). When re-assembling, please follow the numbering sequence. We recommend connecting the pieces part-way by hand, and then finding a hard floor surface (either with a rug or carpet) to tap the rest of the pieces in place until they lock (rubber mallet works great as well if needed). We designed it this way to ensure the airways remain tightly sealed.
