Hardly, they banned fully disposable. You can still by them but now you can swap in a refill cartridge. The price of this refillable one is the same as the original.

Many places apparently don't even sell the refills so it's practically the same.

It was one of those rush laws. They are still for sale, I walk past a "BULK OUTLET FOR ELF-BAR" shop sign when I walk to work.

It's one of those UK laws of "we are doing something!" but not actually do anything. These companies either pay backhand or know how to skirt around the rule. Who's enforcing it?
