post it highlighter

Some erasable highlighters use thermo-sensitive ink that becomes colorless when rubbed with the included eraser, letting you highlight, erase, and re-highlight. Product notes warn the ink can temporarily lose color with heat and that cooling can restore it; manufacturers typically recommend using the product's supplied eraser for best results.

Look for quick-drying, smudge- or smear-resistant inks and non-bleeding formulas. Many product listings also call out inks that resist smearing from common pen and marker inks, helping keep highlighted pages clean.

Highlighters commonly come in multicolor assortments. Typical colors shown include yellow, pink, orange, green, blue, and purple, and some sets use softer pastel shades.
