As I was watching an episode of Inuyasha, I found myself contemplating Kagome's bottomless knapsack. She's so thoughtful, she always brings back modern-era stuff for her friends (ramen for Inuyasha, candy for Shippou, soda and other treats for Miroku and Sango, etc.).
Anyway, that (plus her propensity towards bathing), made this cute idea pop into my head. Heck, she already brings back soap and shampoo - so why not a few other "beauty" products to share with her best gal pal, Sango?
