Looking for ANSI Enter and Shift keycaps

[Tacanacy]

I'm changing an ANSI layout to ISO in my native language and need one ANSI Enter and Shift keycap, in black color, and white lettering or modifiers. I'm also looking for a neutral font, like Arial, Calibri, and Verdana.
I rather not buy a whole ANSI set to over 100 USD only for two plastic keycaps.

Are you looking for MX, Topre, IBM, Alps, Fujitsu Peerless or "Space Invader" keycaps?

Assuming MX, WASD Keyboard would an option, printed or blank.

if you don't find any matching keys, maybe getting an colorful modifier set (eg bluegaloo, ceresia) is an option?

Just throw a pic of your current keyset, it's not clear what keycaps you have (OEM default, aftermarket cherry profile etc.) If you are using cheap keycaps, somebody may send you a full set for 5$ or even for free.
