Arx by Superfried is an elegant and intricate display typeface designed for use at large scale. Its Latin name - meaning citadel - connects with the classical features, whilst the phonetic pronunciation nods to the arcs which characterise each glyph. This caps typeface is available in two formats: fade and solid, each featuring two distinct character styles switched via the shift key. Fade features delicate incisions to add depth and the illusion of 3D shading to the arcs. Solid, as its name suggests, is a cleaner, flat alternative.

The first version of Kremlin was designed at ParaType (ParaGraph) in 1995 by Tagir Safayev. Based on an informal handwriting. Kremlin is a Russian word for a fortress or a citadel. The reason why the author selected this word for the font name is not quite clear even for him. Probably the appearance of the text line set in this font resembled a tight fence. Later the font was expanded in character set and got two style variations with extended proportions. The suffix "Pro" in the name was added to distinguish the new version from the previous one. The derivative work was done by Dmitry Kirsanov and Gennady Fridman in 2010. The font is recommended for advertising and display typography.
