blue highlighters

Many assorted packs include yellow, pink, and blue. Other sets add pastel shades such as magenta, light pink, purple, and blush for more variety.

Erasable pastel highlighters use thermo-sensitive ink that becomes clear with erasing friction (using the built-in eraser). The ink can lose color at temperatures above 140°F and color can be restored by cooling to at least 14°F, so avoid exposing them to high heat.

Some sets specify non-toxic materials, PVC-free construction, and FSC-certified packaging to provide a more sustainable presentation.

Pack sizes range from single pens to multi-packs. Listed sizes include 1, 6, 12, 24, and 48, and classic yellow options also appear in larger bulk sizes such as 25, 50, 100, and 500.

Listed tip sizes include 5 mm, 1.6 mm, 1.0 mm, and 0.4 mm; some items use non-numeric labels such as "Medium."
