Line by Letters from Sweden.
Line is a collaboration between Stefania Malmsten and Göran Söderström. The typeface was originally designed for Swedish fashion and culture magazine Rodeo in 2012 before it was released for commercial use at the end of 2013. Line comes in 5 super thin styles. They can be used individually, or with a formula that keeps stroke weight uniform across different point-sizes. The typeface consists of a basic character set with some alternate letters, plus a large number of modular embellishments which attach to letters in different ways, using kerning pairs. Line is inspired by beauty, handwriting, graffiti tags and scribble.
