"These may have saved my washer's life!"
I used to put my bras in the main wash in a big square net bag, but recently the bras got loose, then a wire got detatched and snapped in the washer. So I was looking for better protection against seriously damaging the machine. The large tangle free bra bag is GREAT. 2 underwired DD bras fit in fine. Bag has contours for the cups, and panels that keep the sides of the bra in place, so the garments and hooks don't thrash around. Plus a neat elastic tab that stopped the bag's zip coming undone in the wash. I now wash bras on their own on delicate cycle but am pleased I can still machine wash.
