It claims that this double injection modelling has increased quality and attractiveness. After using and extensively examining these for
Elux Flow 600 a few weeks, I have nothing unfavorable to say about the design or build quality. The shell's design lines are clear, and there are no flaws in the overall quality. There is only the necessary amount of branding or language written on these. There is a small LUX logo underneath it on one side. The flavour is printed on the reverse side.
