I just realized something: this yellow highlighter, which I have had in my possession for over a year, is an aromatherapy highlighter. That’s right, it smells fruity. We’re talking lemony freshness at its finest! How I never recognized this before is beyond me. Now my problem is…I can’t stop sniffing! At least I know it’s “nontoxic” and “conforms to ASTM D-4236”…whatever that means.
