In the pictures, it looks a lot like
a keyboard I have, which has fake clicky Cherry MX switches with white stems. Rumour has it that these clones were made in Taiwan.
My keyboard has a rubber sheet inside to make it waterproof, but I think that it was modified, with the sheet being in place of a metal plate that the keyboard seems to have been designed for but does not have. The keyboard also came with a clear plastic cover, similar to the one in your pic.
I have seen similar keyboards for sale on ebay.co.uk a few times.
I have heard that similar-looking keyboards exist with ALPS also.
