White sport band for Apple Watch, durable design. - Brand: DONEGANI - Type: Sport Band - Compatible Models: Apple Watch - Color: White I am selling this because I mistakenly bought it on Amazon, thinking it was a smartphone. It is brand new and unopened, and I haven't touched it at all. Looking at the sticker on the back, it seems to be compatible with 42mm, 44mm, 45mm, and 49mm Apple Watch models. Please check the image in the third photo. Thank you for looking.
