nice mostly not plastic [SEP] it is really good to use a toothbrush that is mostly wood rather than plastic granted the bristles are still nylon ie plastic but they are a small fraction of the materialsit works nearly as good as a typical plastic toothbrush the only annoyance is that the shape of the neck a rounded rectangle in cross section seems to make it more susceptible to the toothpaste escaping your mouth which can be overcome with a little care but i wish they would just round the neck more so that it is not an issue
