If you mean the Hair Gel, I do.
Yea can you tell me What the colours Purple and grey are used for :\
and its not gel its wax
idk, wax or gel, i'm not that good at English.
um, I don't think if the color matters. what matters, is what is written on it.
mine is yellow, but under the word Gatsby, it is written "super hard"
that is why I bought it.
how ever maybe only yellow ones are super hard!
I can't believe I'm answering this on a cubing forum!!!!
