Ink-Free: These narrow highlighter strips are made of PET material, so they do not leave permanent ink or cause ink 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 locate and review key information. Removable & Repositionable: Half of each strip is adhesive, allowing easy peeling and repositioning. No more worry about highlighting mistakes—strips stay securely in place on the exact sentence and leave no residue. Customizable Sizes: Fit most books; easily trimmed to your desired length. Each pad includes 5 colors—just carry one compact pad instead of multiple bulky highlighters. Assorted Colors: Great for daily reading, studying, color-coding, or creating a color theme. Share with classmates, friends, or colleagues. Note: Due to variations in production batches, slight differences in color or appearance may occur—this does not affect functionality. Color may vary slightly due to screen settings and lighting conditions. Measurement tolerance: ±1–3 cm. Material: PET Package Contents: 12 page marker tabs Color: As shown Other products not included.
