Honestly, Tvyek is pretty miraculous. It’s permeable to water vapor but not to water, it’s nearly impossible to tear, but can be easily cut. It’s cheap and made entirely without binding chemicals. In addition to being used for wristbands, it’s used to wrap construction sites to keep out water during construction, for tear-resistant envelopes at Fed-Ex, coveralls for mechanics, and my wallet, actually.

The fun thing about finnish is that the way you ask for things in a polite way has been in-baked into the suffixes you use, so you don't have to use many words when few do trick. Like asking someone "could you give me [-]" is "voisitko antaa" in written and some variation of "voisiksä antaa" in spoken dialects*, but instead of asking "could you", the polite polite way to ask is "haluaisitko", not as can you, but would you want to. The tone distinction is so clear that asking someone "could you [do thing]" instead of "would you want to [do thing]" is less of a polite request and more of instruction - someone's gotta do it, and the task is being assigned to you.

Since I use it a bunch in my speech, I also want to shout out "viitsisitkö antaa". I don't think there's a proper english word to translate it with, but the closest approximation of the meaning is "could you be bothered to give me" - however while the tone of the translation could easily be read as passive aggressive, if you're just saying it politely, it moreso has this tone of, like... "if you would be so inclined I'd appreciate it".

One more option is to state "you wouldn't have x" (ei sulla ois x:ää) and that's somehow interpreted as a polite request

You can certainly say "you wouldn't happen to have a [thing] that I could borrow?" in english, too, but I do like how in finnish, the latter half of the sentence is not stated out loud, just implied. You don't word that question like that unless you're asking whether you could borrow it. Which also gives the other person the opportunity to soft launch a "no" by pretending to not notice the implied part. So a conversation can go two ways, it's either:

Circling back to the conditionals - you can also tack the conditional right onto the verb you want someone to do, without the "would you like to/could you/could you be bothered to"

"Viitsiä" as a word is also weird because it has two meanings depending on the region. Somewhere it means "to not be ashamed (to do something)" and somewhere else it means "to not be lazy (to do something)", roughly explained, because it also is synonymous with other Finnish words that just don't really translate into English (kehdata vs. jaksaa). In my area or at least in my family we often add that to sentences when asking for a favour, asking if someone would be in the mood to help with something.

Briteille tuo on haaste, koska ruotsalaiset ovat niin hiljaisia.
