For anybody wondering Beauty Blender ( is a brand but is also reffered to any blender used for makeup - but in this case she mentioned the brand BEAUTY BLENDER) .
It is 20$ each and is hard to get in India since its am international brand. To get it india you would have to pay the taxes + shipping.
I recently lost mine and it freaked me out untill i found it because i know how costly it is and only makeup junkies will get how necessary it is lol mostly people dont use brushes for foundation + concealor + baking + blush + contour when they have beaugy blender with them
P.s Not a Rubina fan but just a makeup lover lol.
