These are my second set of Keytok keycaps (after the Godzilla berry set), and have the same great quality and attention to detail with the design. The full set of 194 keys meets my requirements for a macOS and ISO-UK layout keyboard. This is just a slight personal preference, but I wish a few more of the R4 keycaps had just the icons without the F (function) legends, to allow even more flexibility of choice to use across that function key row.
