There’s a long list of products we love and use every day with our Field Notes, and every so often we kick ourselves and ask, “why don’t we offer these to our customers?” Such is the case with Book Darts, a simple but ingenious invention that’s been manufactured for years in Eugene, Oregon by Jeanette and Bob Williams.

The fusion of a bookmark and a paperclip, a Book Dart can be easily slipped into any book to not only neatly mark your page, but also to point to the exact line where you left off. They’re great for fiction, memoirs, manuals, planners, notebooks… heck, any document or stack of paper you could name.
