Size: 2.6 x 3.6 inches (65 x 91 mm), ultra-thin 20 micron film (0.02 mm), plus 0.08 inch (2 mm) size for standard sized cards. Features: Reliable domestic production. We use a 20 micron film with a focus on the thinness of the film. In addition, it prevents fading by UV rays. (Can cut 80% of fade wavelength) Regular thin inner sleeves are 30 microns but thinner reduce light distortion and are ideal for ornamental sleeves. It can also be used as an inner sleeve during gameplay to reduce the thickness of your deck. It is a clear sleeve on both sides.
