Reversible Zipper Pull Demo Narration

Inputs: [bag or garment reference], [pull mechanism close-up], [approved use demonstration]. Show the documented reversible zipper pull moving to the opposite side while staying attached to its slider. Distinguish a reversible pull from two separate sliders. Preserve tooth alignment and avoid unsupported waterproof or durability claims. Produce a 20-second original voiceover describing the verified side-switching action. Adapt the presentation to [audience] and [tone]. Check the defining task detail against the inputs before finishing.

Use only the supplied facts and approved wording. If a necessary script or timing reference is missing, ask for it first. Produce the audio when supported; otherwise return the complete spoken script with pauses and a short production cue sheet, clearly labeled as a script. Use original voices and keep speech intelligible without music. Never claim an audio file exists unless it was generated.
