No, in general, the smallest block of IPv6 addresses you can "own" is /24. You have to pay yearly fees to your RIR (Regional Internet Registry) as an ANS (Autonomous system). Think of it as owning land and paying a land tax.

I have a /24 registered in the early 90's. I pay no registration fees for it since it's a legacy block.
