Gua sha = face scraper. I already have two. One jade or rose quartz one, can't remember which, in a Birchbox, and a plastic one (shame on them!) in a Glossybox. It was a key part of my decision making this year that I did not want a third gua sha.
Next is my choice as it has fewest drawers of disappointment for me, e.g. black eyeliner, false lashes, tanning products, and pointless tools. Just waiting for Wednesday so I can order.
