As you can see, the image is slightly clearer in the polyester sleeves. Blacks show through better and there is more contrast between the shades. The surface is also more glossy, so there is slightly more reflection.You can also see the difference between how the holes are constructed. On the Cristal Laser sleeves you can see that the holes are on a black strip on the left of the image, whereas on the polyester sleeve the holes are on the sleeve and there is no separate strip.
Due to the different spacing between holes on the portfolio sleeves each portfolio requires specific sleeves.
Below is an outline of which sleeves are compatible with each sleeve.
