삼각형 모양 형광펜

The triangular shape fits perfectly in my hand, making long study sessions much more comfortable. The compact design also means it stays put on my desk instead of rolling away.

Finally, a highlighter that doesn't roll off my desk — the triangle shape is perfect. It's lightweight enough to toss in my pencil case without adding bulk.

The triangular shape makes it way easier to highlight precisely along the edge of a page without smudging. It fits perfectly in my pencil case too, which is a huge bonus.
