One more good production date calculator for cosmetics is http://checkcosmetic.net/
More brands are available, and it calculates better than the website above which seems a bit outdated (some new cosmetics results is 2001-2003 year of manufacture).
Woah! I’m really loving the template/theme of this site. It’s simple, yet effective.
A lot of times it’s difficult to get that “perfect balance” between usability and visual appeal.
I must say you have done a awesome job with this. Also, the blog loads very fast for me on Safari.
