For the bowl, we have three bowl-size options in 14.5: Small, Medium, & Turbo. Turbo is almost a straight bowl, so I'd recommend a glass screen for that bad boy! Unfortunately we don't have any 14.5 joint size diffusers in 11.5cm length. The shortest we carry is 13cm
Could you show me a picture of them? So that I may correctly identify which one I'm after. How much are they as well?
