Glitter on phone cases

[Peggykan]

Hi

I use a 3d sublimation heat press to transfer designs onto my phone cases at the moment and they are turning out quite well.

However, i am interested in adding glitter to my phone cases.

I know that people use glitter heat transfer vinyl for clothing but I have no idea what alternative there is for phone cases. Does anyone on here add glitter to their phone cases?

Also does anyone know of good phone case blank suppliers in the UK for 3d sublimation?
