Yeah, Toanoana is (for the most part) a doujin site, so it's all likely fanmade goods.
That being said though, if you really want them and are willing to shell out the extra money (will need to pay to ship both to the buyer and later international shipment, in addition to any service fees and such) you can always send an email to
http://yokattaweb.jp/index.html with direct links to the product(s) you want to purchase.
Though keep in mind Toranoana being a doujin site, also deals in ero goods. So upon entering the store (maybe even not the store, idk I just always go straight to the shop itself when I'm browsing) you should get a page asking if you're 18 or older, with the 2 options being はい (yes) on the left and いいえ (no) on the right.
Also, if for whatever reason you (or anyone else) decides to do this, for a bit of advice, always buy in bulk. It'll likely cost a substantial amount of money (expect at minimum ¥20000 total product cost+shipping fees+service fees+anything else for good results) but the price per item ratio for shipping and whatnot should be substantially cheaper.
Lastly use EMS. Always use EMS. The safety it has with tracking and insurance already added to it far more than justifies the increased cost.
