Aye!
I agree, I've repackaged large bags of DME...
One day I did it outside. It was around 40F, a little windy, but sunny, and humidity was near 0. None of it stuck anywhere, not even to my skin. It flowed like fine sand. No bags got sticky and the job was done in no time. I didn't even have to wash my hands and arms afterward.
It was like a dream, except, I was not dreaming.
