Removable/Reusable Page FlagsAllow yourself to quickly retrieve data from dense documents, textbooks and personal planners. After the flag is no longer necessary, simply remove it and reuse it.

Plus, for added organization capability, the flags can be written on with a ballpoint pen, pencil or permanent marker—so you can make labels or add notes to the flags. Color(s): Assorted.
