The super fat Razorock F-400 will fit perfectly in the rest of the original one. Most other brushes look a bit lost in it
After buying the real pereira which I loved because it works so well except for heat retention
Ali had a sale on the ceramic copy
Out of 13 euro curiosity I ordered one.
It looks a lot like the pereira but it is smaller, the brush rest unnecessarily wider and the handle is also a little bit different. Does it lather yes it does a tad slower as the pereira imho and I find the pereira a bit roomier and more comfortably in the hand.
It is not completely faultless in the finish some small glazing spots either thin or thick. Now hope it works in the winter to keep lather a bit warmer else give it away or try the breakable feature….
