Which of these would be the best for taking on a plane?

Silicone dildo! It won't set off any alarms. Glass you never know, they may think you will try and break it and do something. I mean the first attack the man had a razor blade, something so small. So, to avoid it all I say silicone.

I took my lelo siri with me in carryon because it has a useful lock feature so it wont turn on. plus it looks like a computer mouse.

yay double post, sorry!

Lelo Mia is the perfect travel vibe. It has a travel lock and it doesn't look suspicious at all. With it's usb charger, you can pass it off as a flash drive or dongle. It's also very quiet, which is nice if you'll be staying with friends or relatives. I took it with me on a trip this summer, and I don't think security even looked at it. I had it in the same pouch with my laptop charger, extra battery, and other electronics stuff.

I think a silicone dildo would be easiest to travel with.

Lol take whatever your willing to be questioned about I guess.

Silicone probably since glass seems too fragile and would probably attract more attention. But you might be able to pass it off as an ornament I guess.

I'd bring a silicone dildo!

Silicone for safety and weight reason.
