ALBLANC Shine Treatment Mask 3 sheets I purchased a Christmas box containing 8 sheets for 11,000 yen. Since each sheet costs 1375 yen, it's a great deal♡ Each sheet is a thick, substantial sheet mask containing a generous 33ml of serum, equivalent to about one bottle of beauty serum. I was planning to give these to an acquaintance, but we couldn't meet, so I'm offering them at a reduced price.
