The 1 lb. bag is my go-to for making DIY face masks, and the fine powder mixes in without clumping. It’s a solid value for the amount you get, and the zip-top seal keeps it fresh between uses.
Ended up buying the 4 oz. size for a travel kit, and the powder is so fine it mixes up in water without clumping, which I wasn't expecting. Already used it a few times and the texture stays consistent, so I'm glad I went with the bigger option later.
Opened the 4 oz. jar and the powder is incredibly fine, almost like flour, which makes it mix into water without clumping. I've been using it for two weeks now and a tiny pinch goes a long way, so the small size should still last me a while.
