The 360metal revolving head enables your little ones to play and run freely, no need to worry that your kids will be tripped over. Built-in with induction lock, safer than an ordinary key lock once locked, kids wont be able to remove the wristbands until they have been unlocked by a parent. Lock and unlock without electricity, no electromagnetic radiation, suitable for newborns.
