This is a protective film to be applied to the glass part of a watch. It comes in a set of 5. It's an adhesive type, so anyone can easily apply it. Also, you can remove it and reapply it many times. The size is 34mm in diameter. The second picture is a sample with a 28mm protective film applied. As you can see in the photo, it doesn't look like it's applied, but due to manufacturing reasons, there is a hole of about 1mm in the center, so please be aware of this. For those who don't want to scratch their favorite watch, etc. In addition, we will respond flexibly to requests such as the number of films and the size of the film, so please feel free to contact us. *If the watch surface is not flat but has unevenness, it may not adhere. Also, please understand that there may be effects depending on the material before purchasing. We can change to anonymous shipping via Yu-Yu Mercari. In that case, the price will increase, so please understand. If you wish, please comment.
