Rosarios4 Solo Latte is made of 100% milk fiber. The milk fiber is extracted from the milk proteins. The dairy fiber is a very smooth fiber and therefore very soft on the skin and because of its smooth fiber, antibacterial properties make it an ideal baby yarn. In addition, it keeps you warm and summery in the winter. Rosarios4 Solo Latte has a silky shine and is lightly painted, which gives a living effect.
