Are these RBG set PBT or ABS from ikbc?

I'm new here. I have a question whether these keycaps are PBT or ABS? Thank you in advance. Appreciated!

How to tell if keycaps are PBT or ABS:

1. Fill a glass with water
2. Put keycap in water
3. If it sinks it's PBT.

I believe ikbc = vortex, as the keycap puller would suggest. Keys also look like vortex double shot PBT. If you're ever unsure about a material, throw a cap in a cup of water! If it sinks, it's PBT, and if it floats it's ABS.

If it's thin not thick caps, when you throw it in the cup you may have to poke the cap below the water level. If it doesn't immediately sink then it's for sure ABS.
