It actually refers to the discs. Typically around 5-6" across, with little notches around the sides to put the threads in and a hole in the middle for the braid to hang as you make it.  These are "travel" or "toy" versions, if you want a lot of braid you really want some kind of stand.

Here is an example from walmart:

OK, I had to look up what kumihimo was (gotta love the intarwebs). Now that I know that, I'm confused about what it being round or square could mean, unless that is the cross-section of the cord. If that is the case, then the question becomes $3 for what, a foot, a yard, a mile?

Not that I plan on buying any. Just curious.
