A little color can change the way you see a page. Portuguese design studio mishmash brings its playful, modern sensibility to this collection of more than 200 stickers in an exuberant palette of colors and geometric shapes. Use them to organize your planner, mark important moments, or turn an ordinary notebook page into a composition of your own.

Five sheets of assorted shapes and sizes, packaged in a glassine envelope, designed and produced in Portugal.
