Greg - I have 2 different ones. Some friends stayed at the New Frontier and brought me one. I don't know about the other one. The differences are: There are 2 small insert arrows at the top of the lighter colored one and the word "Solideal" is at that end when you turn it around - this is the one from the New Frontier. The other one does not have the 2 insert arrows and is a little darker gray and when you turn it around, the word "Solideal" is at the end where the date is.

Hope that helps.

Esther
