As a Finn I can assure you that they are a legit company. I might have bought some random stuff from them but can't remember for sure.
Their website promises US shipping for $21.92, here's the link to shipping info:

Also European laws for webstores are kinda strict, so they'll definitely help you if something goes wrong.
Hope this helps!
