Please make a note that these protectors only fit 2 D ring albums as I own a few with 3 D rings and the holes do not correspond. Such a shame! The size also slightly differs as I had to cut down on some of my completed projects to fit these.
This is just right for what I wanted. I use these to store my stencils above 6x6 but smaller than 12x12. The material is quite sturdy and I can punch extra holes without difficulty (unlike some others) to fit in various size folders.
