Direct Answer
Page Marker Flags (repositionable film index tabs and arrow indicators) are thin polyethylene terephthalate (PET) film strips measuring 0.5 inches (12 mm) or 1.0 inch (25.4 mm) in width by 1.75 inches (44 mm) in length. Featuring a translucent adhesive body and brightly colored tip, they flag contract signature lines ('Sign Here') and textbook pages without obscuring text.

The Transparent Overlay Advantage
Because the body of the flag is made of clear PET film, placing a flag directly over important contractual clauses, legal footnotes, or financial numbers leaves the underlying text fully legible beneath the flag.
