Enjoy fast, effective, and super-convenient teeth whitening with this set of Advanced Whitening Pens from Smileactives. No need for trays or strips, just brush the Advanced Whitening Pen onto teeth and go. This three-piece set includes the new Cinna-Mint flavor inspired by Program Host Leah Williams, plus two additional pens in your choice of Vanilla Mint or Winterberry. How do I use it: After taking off the cap, twist the opposite end until a small drop of gel is visible on the brush tip. For a brand-new pen, several twists may be required to break the seal and prime the brush. Apply a thin layer of the gel directly onto the front surfaces of the upper and lower teeth, and allow it to dry for a few seconds. Replace the cap. From Smileactives. Includes:
