If Possible, Remove the Batteries:  This is the surefire way to prevent a sex toy from accidentally turning  on during transit and discharging all its battery power. Place your  batteries in a plastic bag and store them separately. 
 
Choose Products With a Lock Feature:  If you're traveling with a rechargeable vibrating toy, or one with a  battery can't be removed, check if it has a lock feature. This will  prevent it from turning on, even if its buttons are accidentally  pressed. 
 
Pack Small/Discreetly Designed Products:   Small toys are perfect for travel, as they can be stashed just about  anywhere and are less likely to draw attention. Alternatively, a larger  vibrator with a simple, understated design (e.g. no zebra stripes or  glittery rabbit ears) can be an ideal option. 
 
Pack It Between Other Items:   Rather than let a sex toy roam freely in your carry-on or luggage, pack  it in a carrying case or plastic bag and place it between layers of  clothing. Should your bag get searched, this will buy you time to  quietly explain that you're carrying a sex accessory and ask that your  bag be searched in private. 
Personally I would just buy new ones at your final destination than go through all this crap
