旋轉蓋橡皮擦

The rotary cover is so satisfying to spin—it's a nice fidget while I work, and the eraser itself is just right for fixing pencil marks. Really glad it has a case to keep it clean when I toss it in my bag.

The rotating mechanism works smoothly, and I appreciate how the case keeps the eraser clean when tossed in my pencil case. My only tiny gripe is that it's sometimes a bit stiff to turn at first, but it loosens up quickly.
