Before coming to japan i was confused by "Logitec" Japan http://www.logitec.co.jp/ . Logitec Japan is not the same "Logitec" as the Mouses and Keyboards manufacturer known in europe.
The Logitec brand in europe, is known in japan under the name of "Logicool" http://www.logicool.co.jp/
so, if you are looking for this accessory...you will not find on the logitech website in europe...
