Colgate Wisp ($2.39 for pack of 4 / $7.99 for pack of 16. Each pack comes with 4)
I take the Colgate Wisp every where with me when I know it’s inconvenient to take along toothpaste and a toothbrush. I especially take it with me when I travel. The Colgate Wisp is basically a 3.50 inch long travel toothbrush with a toothpick at the other end. There is a freshening bead in the middle of the toothbrush bristles. It’ll fit practically everywhere: your purse, pocket, luggage, etc. What I like about the Colgate Wisp is it doesn’t require water to work. You just take the toothbrush out of the pack and brush away and use the other end to get in between tight spaces. It’s very travel friendly. The bristles are a tad bit stiff so make sure not to brush too hard. Also, the toothbrushes are a one-time-use thing. You can’t reuse them. There are 4 flavors to choose from: Coolmint, Cinnamint, Spearmint, and Peppermint. Peppermint is my favorite.
