My favorite DX pen + my favorite Sanrio character. The Hello Kitty Uniball Signo DX! Available in .38 mm tip size, in your choice of Baby Pink, Red, Orange, Lime Green, Light Blue, Blue, and Violet ink colors. Refillable. These are limited edition - get them while you can!
I got the Hello Kitty in red specifically for grading papers and editing dissertation documents. The Signo DX never disappoints - I feel like the red in this line is perfectly vibrant and the tip size is very precise. And Hello Kitty spruces up anything!
