The first (released in 1997) and most popular multiple clipboard utility to display, archive and edit clipboards.
Time machine for the clipboard.
See and edit any clip in your history of copies or store copies in the more permanent clip archives. Save multiple clipboards through restarts. Increibly useful, time saver, life saver for all Mac users. The best clipboard app.
