comfortable and earth friendly [SEP] i have tried another model and it did not feel comfortable in my hands i was afraid of getting a splinter and the bristles were too softthis one felt just right not too soft or hard medium bristles for a good clean the curve shape fits great in my hand i like the numbers so we can all use one without mixing them up i would like they option to skip the individual wrap so we can use less cardboard but at least its not plastic
