Thank you for viewing. This is a mini size of ORBIS's whitening serum, "Advanced Brightening Serum." - Size: 7ml (approximately 1 week's worth) This is a sample size serum that I received when I purchased another product on the official website. I won't be using this, so I'm offering it for sale. ☺︎ I received this in the spring of this year, and it is new and unopened. Please understand and agree to the fact that this item has been stored at home for about six months before purchasing.
