Advanced Teeth Whitening Pen

New Original package Choose your flavor 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.
