No matter if you're traveling for business or leisure you're likely to want to bring your vibrator along with you and there's no shame in making every trip enjoyable. Although if your trip includes going through airport security or somewhere else that might want to take a look in your bag, you might want to opt for traveling with a toy that won't make people look twice. Or you might just be looking to maximize every inch of luggage space so you might want something smaller but that doesn't sacrifice power when it comes to sensation. Just keep in mind, there are some parts of the world where your toys legally can't go (like India, Thailand, and the Maldives, etc) so always do a little research before you pack. Even if you're headed somewhere toys are legal, make sure you're bringing something that can't be considered a weapon like stainless steel toys.
If you're bringing a battery operated friend, then make sure you take the batteries out so no accidental buzzes happen in your bag. Plus, battery operated toys should be stored without the batteries regardless. It helps extend the lifespan of your toy and the batteries. So all in all. Just good practice in general. Extra points for discreet battery operated vibes that look like a lipstick like the Tenga Iroha Lipstick.
