This is an Adidas tennis wristband. The size is a bit large, and it's a model worn by male players. The white one is unopened, and the black and pink ones are opened but unused. The pink one is a model worn by Thiem, purchased around 2020. The black and white ones are different models purchased several years ago, but the sizes are the same. Please understand that I will not sell them separately. Thank you for your consideration. adidas tennis thiem wristband Thiem
