Polar Unite, a special hook & loop edition that measures heart rate in real-time. - Brand: Polar - Model Name: Polar Unite - Color: Black - Included Items: Instruction manual, band - Special Edition: Hook & Loop Edition Size M-L Color Black Retail Price: ¥25,000 Thank you for viewing. I purchased this new about a month and a half ago. I don't use it much, so I'm selling it. I used a different band, so the included band is unused. There are no scratches as I have applied a screen protector. I will reset it to factory settings before handing it over. You can start using it immediately after installing the app on your smartphone. The included items are as shown in the photos.
