Labeling Cigars using Post-Its

Hi guys,

I want to keep track the year of my cigars and was thinking of labeling them using post-it. The only post-its that I found are colored. I understand there are cigar wrappers, but I figure the post-its are cheaper.

My concern is that would the dye on the post-its tain the cigars over a long period of time? I looked at my neigborhood Staples and they did not have plain white post-its.

Am I just too parnoid?
