I bought more of these "wisp". Notice they come with two more and in different flavor.
Colgate WISP - is the first disposable mini-toothbrush with a breath freshening bead that allows you to have a clean, fresh mouth with no water or rinsing.
Besides the peppermint they come in: Cinnamint and Spearmint.
Even comes with 2 extra brushes for half a dollar more.
In 1wk I noticed my teeth whiter (I use these through out the day).
