These scented highlighters stack together for easy storage and transportation! Each mini highlighter serves as a cap for the marker next to it, so these highlighters cannot be separated for long. Mix and match colors and scents as you read textbooks, study notes, or annotate for invigorating and engaging study. In all, the set includes six highlighters with six scents. The scented ink is infused with essential oil blends. Blueâocean breeze; orangeâsweet orange; yellowâlemon drop; pinkâgrapefruit garden; greenâspiced apple; purpleâwildflower meadow. The chisel tip makes both thick and thin lines for all your highlighting needs.
