Ink-Free: These narrow highlighter strips are made of PET material, so they do not leave permanent ink or cause bleed-through on pages like traditional highlighters or pens. You can highlight freely without defacing, damaging, or devaluing your books. Wide Applications: Ideal for rental books, library books, textbooks, documents, and files—perfect for highlighting text or sentences to quickly identify and review key information. Removable & Repositionable: Each strip has a partially adhesive surface, allowing easy peeling and repositioning. No more worry about highlighting mistakes—strong enough to stay in place yet residue-free when removed. Customizable Size: Fits most books; easily trimmed to your desired length. Each pad includes 5 colors—compact and convenient for classroom or library use instead of carrying multiple bulky highlighters. Color-Coded Organization: Great for daily reading, studying, color-coding, or creating visual themes. Share with classmates, friends, or colleagues. Note: Slight variations in color or appearance may occur between batches due to manufacturing differences—this does not affect functionality. Color shown is representative; actual product color may vary slightly due to lighting and screen settings. Measurement tolerance: ±1–3 cm.
