Type of keycaps on k70 rgb vs. regular k70

As the title implies, I was hoping to find out whether the corsair k70 rgb has pbt or abs key caps, in addition to finding out whether the regular k70 has pbt or abs key caps. I was also hoping to find out if I can buy the regular k70 key cap set, even if I buy the k70 rgb keyboard.

Thanks in advance for the help,
