This past week I received from Influenster, my newest VoxBox, in it was the Colgate Optic White brush with the whitening toothbrush and the whitening pen that goes right inside the brush! Whiten on the go for sure. I tried it for the first time this morning and my teeth are still feeling clean! I love how easy it is to do, no mess with the whitening pen and no rinse either. The brush is great for taking on the go, which I do because I love to travel so much.
The verdict? A handy brush with a great whitening pen.
