What first enticed me to Kasaa's stationery was the knack with which patterned and multi-coloured papers were combined in a way that was cohesive yet visually stimulating at the same time. One signature style of Kathrin (the brain behind the work) seems to be the accordion-styled file, which she does with much aplomb.
