Comments about Gepe Gepe 2x2 Standard 35mm Slide Mounts with Metal Masks, (24 x 36), Glassless, Pack of 20:

Great overall product. Once in a while, when scanning old slides, I find that I need to remove one from a warped or damaged cardboard mount. These simple yet durable plastic mounts have been a great replacement. I can even remove the slide again, by simply unsnapping the mount, if I need to.

I have found only a couple of drawbacks. One is that these mounts can sometimes be a little hard to snap together. Another is the fact that, if I need to write any info on the mount, I have to add a piece of tape. Ink will not adhere to the plastic. Also, though thin, they are still slightly thicker than the standard cardboard mounts they are replacing.
