Finding the Right Tools for Seamless Pink Gel Application

Question
Dear Liza,
I wonder where I can get a tool that I have seen the Vietnamese techs shape the
pink gel for perfect curve, so that when they apply the white gel, the border
between both gels is perfect and smooth? The tool is a metal sort of disc with
different sizes of sculpting curves at the edges...  Thank You!  Margaret

Answer
hi margaret
i'm really sorry, I havent seen anything like this!
are you sure they are using gel? as they usually use acrylic.
I know they sometimes shape the smile line with the back of a tip?

where are you based and what products are you trained with?
