Praktika Rounded shares the same seven weights and three widths found in the original Praktika family, as well as the same familiar Open Type features:
• Built-in small capitals
• Both lining and old style numerals, in tabular or proportional form
• Superscript and subscript numerals
• Many alternate characters
However, if you can't decide on whether you should get original Praktika or the rounded version, they are also available as a bundle for a rather lucrative price.
