Thank you for viewing. This is an ELECOM TK-FDM106TBK, a full-size membrane keyboard with a Japanese layout. I am selling it because I have replaced it. There are absolutely no problems with its operation. I have removed all the keys once and cleaned them. (Dust is noticeable in the photos, though...) For detailed specifications, please check the URL below. https://www.elecom.co.jp/products/TK-FDM106TBK.html I would appreciate it if you could understand that this is an older item.
