Binder page "lifters"

I'm not sure why I didn't check this out when I was buying pages from Costco (still a great deal) but they also offer in their online business section Avery "Triangle Sheet Lifters" -- these things are fantastic as they are large and work very well with card pages. The smaller ones (not triangular and much more narrow) can sometimes "catch" the pages. At $1.11 each including s&h, I'm ordering more for all of the binders I have that need larger page lifters.
