Review (3/5): There's one problem about these....
Seems to me, since many people mention this on all these sorts of combs/holders, that dividing up the selling packs into "mostly light" combs and "mostly dark" combs, you'd get a LOT more sales! I have light hair, I would happily buy a "mostly light" set (say, 3-4 light and 1-2 dark) -- but all the folks reviewing with "I got nearly all dark combs and have light hair" makes me not ready to buy and end up a set of dark ones!
It shouldn't take the seller that long to sort out their incoming huge order by comb color, and then -- for a "light" order, pulling 3-4 light ones, and 1-2 dark ones for the customer. (And the reverse, of course, for someone ordering the 'dark' set.) (Or, even better, doing ALL light and ALL dark and half-and-half...)
