This "Natural Color" series features gentle colors inspired by nature. These are great for emphasizing text without using fluorescent colors.

FriXion highlighters use a special thermo-sensitive ink that turns invisible when rubbed with the built-in friction "eraser." The ink disappears cleanly without using up the eraser or creating any dust or smearing. The ink will also disappear if exposed to other sources of heat or friction, so we advise against using it on envelopes or leaving anything marked with FriXion ink in a hot car. Like magic ink, erased FriXion ink reappears if placed in a freezer or otherwise exposed to temperatures below 14° F (-10° C).
