I love a good lip balm. So how does this nipple balm hold up, on my lips?

Dr. Lipp Original Nipple Balm for Lips $14.50

So while, I can see why its probably awesome for nipples, as a lip balm its pretty great. I originally got this in my BirchBox last month, and immediately bought it full size. It was instant love.  It totally holds up and really moisturizes. It provides the best base for so many lip products- lip stains, lip gloss, lipstick- it instantly earned a spot in my purse, its really that great. Oh and it lasts for like ever.
