Panic the makes of shockingly good mac software “has been granted a license by Namco to sell a line of t-shirts inspired by the cult-hit Playstation 2 game Katamari Damacy!”(~stevenf)
All of the shirts are 25US$ and besides the Katamari soundtrack these are the only licensed items Takahashi himself has ever approved.
“Unfortunately, due to our licensing agreement, we can only ship to the USA, Canada, Japan, and Korea at this time. We’re working on adding more countries, so hang in there.”(~stevenf)
Buy them at Panic Goods.
