Ooh, different colors for different capsules *ponders*
Yeah, you can't use them for wet stuff, especially in the darker colors, as you can get dye transfer. That and the fact that you can't rotate the hanging hook like you can with the clear plastic kind are the only downsides for me. But they do save a lot of space and necklines stay put. I don't use mine for skirts or pants, just for shirts and dresses. I've got different pant hangers and skirt hangers.
I think I used the endless stream of BB&B coupons to get mine, a 10-pack at a time - but I'm sure there are deals for the larger boxes too if you want to do it all at once.
I wonder if the fact that I'm on the larger side is why I like them, and that I never liked the clear plastic or plastic tubular ones so much? I've often had tops/dresses that are too big for the width of the hanger, but never anything that was too small and hard to get on. That's what you get with size 14 and 5'9" I guess - I can see that more petite ladies would want a sized-down hanger. I finally sourced some extra-large hangers from Target for my 6'6" DH which are really great - before, his shirts always ended up with wrinkles at the end of the shoulders because the hangers weren't wide enough.
