Our patent pending In & Out Pages™ let you safely remove a sheet from any pad, work on it, scan it, and put it back anywhere, anytime. The special dome shape of the paper edge locks into the dual wire binding, keeping it in place.  A fine perforation allows you to remove the Domelock™ edge to get a true sheet size should you wish to mount and frame your work. Available in drawing, sketch, bristol and colored pencil lines.
