Is the yellow side suppose to have a full circle or is that top corner suppose to be like that?

Woah... I'm not sure if that's how it's supposed to be, since I don't own any of the crazy tetrahedra, but that's certainly odd.

No,it should be a circle all the way around but I can't remember if they did a version with a plain face?

Definitely should be a completed circle.

I had a similar problem with the super 5-layer pentahedron I got. Did you buy it from nowstore? I'm (reasonably) sure Calvin would send a replacement part for it.

I got it from Mefferts. I'm not going to worry about getting it replaced, I was just wondering if that was how it was suppose to be. I'll just keep it as is.

Thanks for the replies, everyone.
