Private label on this mold
YH557B charges over USB and feeds a cotton wick from a refillable sleeve. The dial on the cap trims the output by hand, which suits buyers who want one hardware SKU across several scent strengths. Unit price is not listed; the desk answers against Incoterms once quantity and destination are known.
Black is the catalog finish; cap and barrel can be moulded in the buyer colour.
Printed or laser logo for private-label runs.
Wick filled to the buyer scent list.
Colour box and user manual printed in the buyer language.
