namashashins are those collectible photos of the groups/idols, oficially released or not. I collect only the official ones, like those that come with cds or those monthly trading photos released by AKB48. I don`t buy those sold by street hawkers next to concerts, for example. As I`m a sucker for collections, getting these photos is an important part of the fandom. probably I would not be THAT into Afilia if they didn`t have those photos, like BiS or denpagumi.inc.
and speaking of that, I dunno if you guys saw it, but they opened a new store that sells only idol goods at Akihabara, the Idol Yokocho store (yep, that one named the recent music festival). it is a tiny shop in the seventh floor of Sofmap`s main store (the one that has AKB48 stuff in the first floor and anime related posters in the walls). despite being small and having limited products from a few groups, it is still an interesting place to go and, to Afilia fans like us, an OBLIGATORY stop.
I went there last monday, the opening day. I can vaunt of being one of its first customers.
it had three designs of Afilia shirts, Whittism towel, all the cds, uchiwas (hand fans), a pocket photo album and a lot of namashashins.
already spent some bucks with them and I hope you can get there soon and buy some stuff too, so we can start trading!!
cool thing is that not all the sets are randomly sold, so it`s not that difficult to collect them.
edit: you can take a look (dunno if you can buy overseas or something) at their website
http://idolyokocho.idolbeats.jp why they don`t have all the products also available in the website is a mistery.
