GreEn nashi pears going relatively cheap. Usually $5-6/ kg even at the markets. I bought a couple of KGS at Jamieson ACT.
I've just edited the title given it was misleading. '21 seiki' is '21st century' in Japanese which is what these are called in Japan and which you'll sometimes see in Australia. You don't get 21 nashi in a kg (thanks to JV for pointing it out).
They must be very tiny if there are 21 of them in a kg…
