Coupang sells Etude eyeshadow palettes, specifically 6-pan containers.

I have exactly 12 single eyeshadows, including the glow eyeshadow I bought recently (purchased little by little with leftover points).

If I buy two packs of 6-piece sets for 5,000 won, I guess I'll be done.

I'm not sure when they started selling it, but SSG doesn't sell just the shared case; it seems they only sell it on Coupang.
