【Product Description】 Sports bands in white & black and yellow & gray. I purchased these for a series 5 40mm, but they have only been used a few times and are in very good condition. I have confirmed that they can also be attached to the latest series 10 42mm case. They should fit the smaller size of each series without any problems. 【Comfortable Fit】 The silicone band is soft and made of skin-friendly material, making it comfortable for long periods of use. Thank you for viewing.
