I'm still in this Project Doll test group. I just got this email:
Congratulations, you've been selected as a sheet mask tester for Project DOLL! As mentioned, this project is a week-long product test in which you will be asked to use 1 sheet mask a day for 7 days and then log your experiences mid-week and at the end of the week. We will update you more once the products ship, so stay tuned!
PRETTY STOKED. I effing love sheet masks!
