I'm selling these because I bought them a few months ago but am using something else. It's a set of two! Apparently, it's a very popular product, and the serum really absorbs well. I've repurchased it about three times! The fragrance is nice and not overpowering, it's really good! A small amount is enough, so I think it's cost-effective! Although it's a new, unused item, please understand that it has been stored at home. Immediate purchase is OK. First come, first served!
