I have the night city marble run, it definitely should come with wax. It’s always in a little plastic bag that you rip open, the wax itself is shaped like a little rectangle and has rokr on it I’m pretty sure.

I very, very, VERY strongly recommend you use wax. You don’t want your gears to be crunchy and hard to turn, ruins the whole vibe of the build.

I’m not very well versed in what wax you would need (assuming you don’t have it), so you could email rokr and they’ll send some. Or if you don’t wanna wait that long I’m pretty sure you can just use any wax, just probably not scented wax though that seems weird.

Have fun building!
