### ⭐⭐⭐⭐⭐ Lo voy a poner a prueba

### ⭐⭐⭐⭐⭐ Why packs of 3?
*by M***E on 18 October 2021*

I have absolutely no idea, why these come in packs of 3? I have the fx6, so I require 6, to fill the trays. The fx4 requires 4? This is not too bad for me, as I buy to packs and sorted, the fx4 owners must be fuming? Why not pack in two's makes much more sense? These are relatively expensive for what they are as well.
