The merchant has provided specifications (Brand Name: NONE, Origin: Mainland China, Voltage: 24v) for a wearable hands-free fan product. However, there is no instruction to modify or add to the existing description. The current description already contains these specifications in HTML format.
Since no explicit instruction was given to change, rewrite, or add content, and no excerpt was selected for editing, I will not output anything. The existing description is already in place and matches the provided specifications.
