This is probably my favorite Birchbox sample of all time - I saved up to buy a bottle, which I am certain will last for ages.
At first, I didn't really care for it. I thought it was too strong in the bottle, a bit mature for my taste. But I put it on one day and was converted. Once on it mellows, and smells like an afternoon out of a history book. A unique scent - but be careful, a little goes a long way. Definitely a high quality product.
