Thank you for viewing. INKO USB Wearable Heater Model: PD-S2701 Size: 20 * 20 cm I used this twice inside my coat during a business trip to the northern part of the country. However, I'm selling it because I found a heated vest to be warmer and haven't used this since. *Please check the website for product details. There is some sagging of the heater fabric due to use, but there are no scratches or tears. I have also confirmed that it powers on (see photo 6). This is a used item stored by a private individual, so please consider the description and photos before purchasing. *The box will be folded and included (see photo 7).
