Heated knee wrap in grey, controller docked on the outer panel.
Graphene Heated Knee Massager with Vibration

- Graphene heating, three levels
- Vibration with three patterns and five intensity steps
- Magnetic controller with USB-C charging
- Wrap shape follows the knee; packs to 375 × 148 × 35 mm
- 27 units per carton, 534 g per set
Where It Fits
On the BY-308 the standard build is: Functions: Graphene heat, vibration; Heat levels: 3; Vibration: 3 patterns, 5 intensity steps. It ships with 1 knee wrap, magnetic controller, USB-C cable and user manual in a Gift box + sleeve. Every quote carries the carton data on the PI, so freight is calculated on the numbers that actually ship rather than an estimate.
Heat film, not wire
Graphene heats evenly across the panel instead of in lines, which is the difference buyers feel on a sample in ten seconds.
Vibration steps
Three patterns at five steps, so the same wrap serves a stiff knee in the morning and a sore one at night.
Units per carton
Flat-packed at 35 mm thick; a carton is small enough to move as a standard parcel.

Price by Quantity
Indicative FOB Shenzhen unit price for the standard configuration. The binding price is on the PI and is held for 15 days.
| Quantity | Unit price |

| 500–999 pcs | USD 9.50 |
| 1,000+ pcs | USD 8.50 |
Freight, duties and destination registration are quoted on top of the unit price. Ladder pricing applies per model, not per shipment, so mixing models in one order does not drop the band.
Retail Box and Export Carton
Carton data decides the freight quote, so it is listed here rather than sent as a PDF.

|---|---|
| Units per carton | 27 pcs |
| Carton dimensions | TBC |
| Gross weight | TBC |
Battery capacity and carton weight are not on the factory panel. This is a heat and vibration wrap, not an air-pressure knee device — the copy says so on purpose.

What Buyers Ask About This Model
What is the MOQ for the BY-308?
The ladder starts at 200 pcs. Below that the model ships as a stock unit under the Imazing label, and on some models there is room on a running batch — ask before you assume the answer is no.
Can you print our logo on the BY-308?
Yes. Logo on the housing, your artwork on the retail box and the manual. Tooling and print setup are quoted per project, and the print proof is approved before production.
Can we order one sample first?
Yes. One unit is quoted at the sample price and leaves Shenzhen in 3–5 days by express. The sample cost is credited against your first bulk order.
Which parameters are still open on this model?
Every field marked TBC is not yet fixed in the factory datasheet. We send the signed datasheet before you list the product and confirm those values in writing on the PI, so your listing never carries a number we cannot hold.
Which documents come with the BY-308?
We release the test reports we hold for the standard configuration — CE EMC, FCC Part 15 and RoHS where the model has been tested. Destination registration (EU authorised representative, FDA listing, EAC, PSE) is agreed in writing before production; the buyer is the importer of record.
