I use these page protectors with the We R Memory Keepers scrapbook albums. I have used these for years, and they are awesome for any three ring binder type albums. I've never had one of these page protectors rip or tear ever, but I've had some other brands that have. I get these in both the 12x12 and 8.5x11 sizes.
Of all the page protectors I have bought these fit perfectly everytime. This is the only brand I buy now.
These things are a rare find. I love it. Perfect for 3 ring albums.
