I was sent three UGLee pen to review and am amazed at the quality. My hobby is papercrafting and my ink pens are forever rolling off the table, under my craft mat but never where I can find them at a moments notice. The comfort grip has prevent rolling. It is also one pen that will not fall out of your pocket. I love the color contrast of the yellow and black metallic grip. The comfort grip is large enough for any hand size. I have arthritis in my wrist and the pen shape provides enough support to reduce fatigue. Let's talk about the ink. It is stupendous. It flows easily and the color is blue when wet and dries darker. I can use it to outline or add texture to my art work. Needless to say I am impressed.
