This auction is for 1 colgate optic white Whitening Pen. These pens are brand new and in bulk box. I do not have them in any kind of blister packaging.

This professional-strength whitening serum is meant to be used with the rechargeable LED whitening device that is included as part of the Colgate® Optic White® Professional Take-Home Kit. But, you can use it with or without led kit. Provided below is the link to the description of these pens.
