Magnetic effect press ons?

I absolutely love magnetic manicures, however I am disabled and the whole process of using magnetic nail polish is way too much for me to manage. I have recently started to dabble in press ons and have been trying - and failing - to find a set with a strong magnetic effect look.

So does anyone know of any, or am I trying to find something that doesn’t exist?

I’m UK based which likely limits what I can get unfortunately.
