Not only do they have an extremely comfortable grip, but, the smoothness when writing is perfect allowing for a smooth continual flow

good grip, writes well, what more can you ask

The grip is smooth, not too bulky and tapers to a smaller size at the end which keeps my finger from becoming sore when writing for a long period of time.

The retractable mechanism is very durable and has not broken unlike some other (more expensive)r pens from other brands.
