i-Clip page markers are a terrific help for organizing my Celtic art reference books - colorfully and conveniently marking the various sections and designs for easy reference. I am hooked; I've purchased at least half a dozen sets for gifts and personal use. Although they do make great bookmarks, I've used them mostly for organization - having a set of coordinated markers works perfectly for marking different sections of various notebooks and journals. So far (about 1 year), they've held up very well, and they're an attractive, fun way of keeping things together. Now that I've had and used them, I wonder how I got along without them previously!
