Now bras using magnet or normal hooks?

Women no longer have to worry about dowdy bra hooks creating unsightly lines and bulges beneath their tops. Lingerie marker Gunze has designed a stylish medal-shaped magnet hook for bras. The two magnets are firmly attached and fasten very easily. Pulling the bra from the side or sliding it up and down won't open it.
