Does this mechanical keyboard exist?

Bluetooth (4.0 or above) + backlit + full size + cherry mx blue

You mean like a bluetooth dongle? Or something like a usb-to-bluetooth converter.

Yes it doesn't really make sense, but just wondering for certain scenarios.

Thanks guys. Actually asking for scenarios like using the mkb on a laptop/tablet with bluetooth ready, so I guess no need for the bluetooth dongle.

Yes you guys are right, only one I'm aware of is the filco majestouch 2 convertible, although no backlit.
And yeah I went to UZ, they only have the TKL convertible, no full-size convertible.

I'm aware it all doesn't make sense , so I'll just opt for using USB.

Not sure which is best bang for bucks,
but I'm probably getting a Ducky One Blue Frame, Blue LED, MX Blue.
Hope it's worth it.

Planning to get the Ducky One blue frame, blue LED, cherry mx blue.
Any advice whether it's a good buy?

Also, any idea why most places don't have stock for this mkb?
Most have cherry mx red and brown only.

Understood.
But good buy though? Worth it?

Then ah, can recommend a full size, cherry mx blue, backlit mkb?
PBT keycaps if possible.

Thanks. Yeah UZ has the blue frame, but no cherry mx blue.
