Quantity: 2 [Specifications] Medium-sized square tip, green / Fine-sized tip, orange [Product dimensions] Shaft diameter φ13mm x length 142mm [Ink] Water-based dye ink This memorization pen serves two purposes: coloring and writing. It combines a green pen that covers over text and an orange pen that conceals the writing itself. Both pens can be covered with a red sheet for efficient memorization. The green memorization pen covers text in textbooks and reference books by covering it with a red sheet. The green ink resists bleed-through, eliminating the frustration of messing up the back of the page. You can also quickly erase and restore what you've memorized with the dedicated eraser pen (sold separately). The orange pen can cover writing in notebooks and workbooks by covering it with a red sheet. Using this orange pen to highlight important points when taking notes makes reviewing before a test a breeze. ●Water-based dye ink ●Pack external dimensions: 40mm wide x 200mm long ●External dimensions: Shaft diameter φ13mm x length 142mm ●Materials: Shaft: R-PP, Cap and tip: PP ●Ventilated cap *The orange color of the memorization pen cannot be erased with the memorization eraser pen. *Once erased with the memorization eraser pen, it cannot be overwritten with the green memorization pen.
