I bought the dual Scarlet/Violet pack with this in mind. I had originally planned to just do the 8 gym badges until I found an Etsy seller who had badges for all 18 types available.
With the Kalos set, I originally had the 8 flat badges on the left, but recently found the more 3D set. The bug badge is so shiny I can see my reflection in it. I will probably put the flat set on etsy
