Go for a portable one. Be clean and proud. Nobody is gonna ask you about the flask-thing anyway unless they want one. https://www.happypo.de/ No idea if it has a translated site, but it's quite butt-forward anyhow.

Said something sarcastic (about expecting no reanimation if she fell off a table) as I met her by coincidence and she bit back harsh and quite colorful.
Stumbled upon each other 6 month later and I recognized her. I shouted a greeting from afar - she thought it was another sarcastic remark, because she didn't hear it all and answered accordingly - I couldn't hear her clearly as well and took it as a greeting. Then we had a short talk which was very interesting and nice.
And that's that. Five years later, she still hasn't strangled me in my sleep. Perhaps it's the long game. Awsome person.
