Kana or language shift keys. It is a Japanese keyboard but has the nice feature of having a usable space bar but has the downfall of having a small backspace key. I'm not sure it is worth shipping in mostly due to the layout issues. But if someone wants one and is willing to pay for it why not.
The main reason I'm not sure it is worth it or not is that most of these I have seen in the past have gone for around 7,500 - 10,000 yen which would make it very expensive indeed after all the conversions and expenses. I tend to only bid on relatively cheap stuff or on something I really want. At current rates and expenses a 3,500 yen keyboard will cost you about $50 bucks before shipping. Right now this particular board is sitting at about 1,500 yen but when all the bidding is over I would not be surprised if this one does not go over 5,000 yen. There are others listed as well but they are much more expensive.
I thought I had found another elusive Topre board and if it had been what I thought it was I would have paid what the seller wanted for it (9,800 yen) but it ended up not being what I thought it might be so I'm passing on that one.
Some other nut case has one of those NISSHO boards I have but the nut pulled all the keys and put them on a Realforce 106 and listed it at 10,000 yen. I guess he thinks someone will pay extra for the cupped keys. Oh he also put the Realforce 106 keys on the NISSHO and listed it for 5,000 yen. If he would put the keys back where they belong and left the NISSHO at 5,000 yen I might get it just to have a unmodified version of it.
Oh well I'm typing more stuff than you wanted to know so stopping now.....
