The "full white" are the same sort of double shot keys used for Klaxon and other SP group buys on here.
Here is what the white look like with black modifiers

Also there's a picture of them on the SP site on a keyboard..

As for their name, going by the site they are called "standard double shot sets"
Both the SP keys and the WASD are ABS material, however the SP keys are double shot meaning the writing on them will most likely never fade at all, whereas the WASD keys are only laser etched.
Thanks, I already emailed them asking what profile/keycap family they use for these white ones, and if I can choose the profile (they have 6 different ones).
I saw the pic on the website and yours. How do they feel? They are rounded/softer... are these "sculpted" or non-sculpted" as SP calls them?
