Same stuff at 1/3 the price
I purchased the top rating whitening pens previously which only came with two pens.  After real closing looking (blowing up pictures, etc.) I thought this may be the same stuff, probably both made in China, as the other one so I bought it.  The pens and the gel inside appear to be completely identical.  Only the box is different.  This is 1/3 the price too!
