For those interested, this particular kind of design is known as retrofuturism around the Internet. Reddit has a good subreddit on it: https://www.reddit.com/r/RetroFuturism/
In addition to being dirt cheap, I also found the branding funny. Somehow I felt like I am buying something not very good in terms of quality, but which does work (somehow) anyway. There were also pack called Lada's in there. I definitely felt like the Sputnik ones were better than the Lada's though.
