You will definitely find this interesting and may even like the journals (like I did). Dreams Away Spiritual Gifts has a page of Warhammer 40k coffee mugs, pillows and more on their site. Its an interesting direction for the GW License and these are officially licensed products.
This was noticed by Denzark on the Bols Lounge last night.
You can also read the rest of the thread where Denzark checked with GW contacts and it appears legit.
