I haven't really kept up with 2x2x2s and have a question. Are there any good quality 2x2x2s generally available with an edge size of 3 to 4 cm? I believe the new Rubik's is 4.5cm but that's too big and the original Pocket Cubes were the right size but of variable quality and not sure if they are made any more. I don't care about corner cutting but it has to move as well as a big Eastsheen 2x2x2 at least. Obviously I am not interested in KOs (assuming they even exist for 2x2x2s) and they have to be generally available, not just the odd one on ebay.
I have of course done some Googling but couldn't find any.

Just because there is no such cube.

If I'm right the only ones that are smaller than standard ES cubes are the standard Rubik (What obviously not as good quality as you want) and the mini ES (What is too small)

The only KO 2x2x2s I know of are some that copy the Eastsheen design directly, which is patented. I accidentally bought some mini-2x2x2s once thinking they were ES but the low price should have tipped me off (here).

I imagine the smaller Dayan 'Zanchi' 2x2x2 will suit your specs, but of course, it has yet to be released.

Edit: having just checked, HKnowStore actually have it in stock already, but it is 46mm (the larger is 50mm)

Too big.

Too small?

Thanks to everyone trying to help but the requirements remain the same as stated in my original post.

You could try making a mini Eastsheen 2x2 bigger by using extensions.
