I would recommend Amazon. There's a box set with 7 of the books, but it'll set you back about $80. I got Moominland Midwinter in hardcover and it's one of the most beautiful printed books I own. There's a few like those, but they're individual and a bit more expensive.
any success on getting VPN to work? I selected Finland (NordVPN) and it's not working. Still blocked. to be honest, it's available with other You-Tubers but I don't want to go down the route of piracy.
I dont know how harsh piracy laws are in your country, and if you are willing to watch pirated movies, but if you are, then you can download the program streamio to your computer and then click on the puzzle-piece icon in the topright corner, and then add the "Torrentio" addon there. then can you simply search on "moomin" and the series will appear where you can watch it in english and some episodes in swedish or suomi. Hope this helps.
Search "Tanoshii Moomin Ikka" on YouTube and you will find some videos.
If you want to buy the BD Edition go here: https://www.amazon.com/Tanoshii-Moomin-Ikka-Blu-Ray-VIZG-5003/dp/B009QQR0S4 (Apparently it's only $2,883.35)
Yeah it’s available on Amazon: Marushin Moomin Mini towel "Moomin Valley Map" https://www.amazon.com/dp/B079HS1595/ref=cm_sw_r_cp_api_i_cMgtEbQY1PB7R
They have a lot of official Moomin goods actually.
It's part of the book series. Here's a link to the box set. Here's a link to the book.
