Polarizing film that can be used for LCD repair of Game Boy Color and other devices. It also seems to be compatible with Game Boy Advance. Size is 123mm X 70mm. It has adhesive, so it can be easily applied. Thin protective sheets are attached to both sides. The protective sheets are printed with marks, lines, and alphabets in color ink. The printing may not be exactly as shown in the photos. It's slightly warped, which is difficult to see in the photos. There were no problems at all with its use. I've just started using Mercari, but I have a lot of experience selling on other flea market sites, so please rest assured. It will be shipped by regular mail with cardboard reinforcement. Mercari shipping is also available. In that case, please add 150 yen to the price and comment.
