How I remember those old protectors that had those black paper inserts yuck. The three holes in the main part of the left side of the page... Thia is much better.
Have you seen the prices of scrapbooking page refills? The quality of these pages is just as good in my book (pun intended). I decided on the "standard" quality because I didn't want the extra bulk and weight of the heavy duty pages - plus they won't be handled enough to warrant the heavy pages. The 5 star is for them being what they are - standard. If you want a "better quality " buy the heavy or nonglare version.
I have about a dozen different binders to organize all sorts of things from knitting patterns to important documents and I find these protective sheets the perfect organizing tool.
