Who this model is for, in one paragraph
Knock Knock sits in the compact end of the catalog, where the decision is about size and discretion rather than the number of modes. Use the specification table above as the whole answer: the published waterproof rating, the control type and the charge method are the three values that decide whether it fits a bedside drawer, a travel bag or a shared bathroom. If you are choosing between two models at a similar price, compare those three rows rather than the feature list — an IPX6 rating and a wireless remote that works through clothing matter more after a year than an extra pattern. For trade buyers, this model follows the same MOQ 300 per SKU terms as the rest of the catalog, and the guide to reading reviews explains which complaints are about the device and which are about the seller.
The same unit in three retail versions
A wearable leaves the line in one form and arrives on three shelves in three boxes. The differences are all in the packaging and the label block, and they are the part of a private label order that gets specified last and reprints first. In the United States the carton carries a 12-digit UPC-A barcode and the name of the importer of record; the radio module is authorized under FCC Part 15 and the FCC ID is printed on the device itself, not only on the box. In Great Britain the same unit carries an EAN-13 code, the name and address of a UK Responsible Person, and a CE mark — UKCA is a voluntary alternative rather than a requirement, and if it is used the mark must be permanently affixed to the product from the end of 2027 rather than printed on an accompanying document. In Australia the RCM mark covers the radio and the EMC of the unit in one symbol, and the Australian importer takes the place the UK Responsible Person holds in Britain.
For a purchase order, four lines settle it before the deposit: the barcode symbology and the GTIN range the buyer owns, the exact wording of the responsible-person block, the language set of the insert, and which market’s mark is molded into the housing rather than printed. Knocking out a molded mark is a tooling change, not a sticker. The OEM and private label terms set out the quantities at which each of those becomes economical, and the certification pack for distributors lists what ships with the first carton.
