They seem to be proud of their Easy PLA. Nothing out of the ordinary that I can see except the 0.85Kg. At first I thought "package downsize" but then I wondered if this filament is formulated to be lighter per meter than more basic PLA's. Its an academic question of course, but there is no reason this filament should be behaving as though it doesn't want to flow.

Fun fact on those short "pen pack" or "pen spool" that are not otherwise promotional, they are formulated for a about 10 degrees C less operating range. I like using the variety packs because it gives me colors galore and I know most of it becomes a no fuss print process. Sometimes I think too much tech got into our plastics.

Anyway, I say this only in response to your flaming zotz experiment. There is something weird about that filament!
