After sseing this filament (Leon3D) in Leroy Merlin several times, I bought one kilo of PLA filament to test it.
The filament comes in a regular box with some windows to see its color.
It comes in a vaccum sealed bag with a packet of silical gel inside.
Rolling of Leon3D filament
As I am familiar with FFF World Optiroll rolling method, Leon3D rolling seems to be worse that Optirool one.
But until now, I have not any issues with the rolloing of the filament while I am printing.
You can see a photo of the coil here.
