Dual PEI Plate textured and smooth (not really smooth)!?

Hello all,
I bought this double side pei texture and smooth build plate.

But for me, the smooth side is not really smooth. Yes, it is smoother then the textured one, but I want to have a flat (like glas) one.

What build plate without texture, do you have?

Thanks for your help and recommandetions


I have Fysetc PEI plates, textured and shiny but not like glass. You could get a glass plate, perhaps a mirror tile of the same size held in place with bulldog clips instead of the PEI plate. I don’t like glass as I get it to stick too well and end up with chunks out of the glass, but it wasn’t toughened glass.
