Muffin is a soft and rounded humanistic low-contrast sans serif based on broad nib writing. It comes in five weights ranging from Regular to Black. The friendly character of the font becomes even more pronounced in the darkest styles. Muffin is well suited for food packaging, menus, children’s products, while Regular may be easily used for long runs of text. The font was designed by Natalia Vasilyeva and released by Paratype in 2017.
