I purchased this in October and am selling it because I stopped using it after one month. Approximately half remains. The amount was measured on a scale, but this includes the weight of the container. It's expensive to buy at full price, so how about it for those who want to try it out?＾＾ The bathing period is about one month. With a baby bathtub, you only use 5-10ml per bath, so I think this should be more than enough＾＾? #Collage SkinApe Bath Additive 500ml #Childbirth Preparation #Baby #Newborn #Bathing Thank you.
