Great for sublimation 3mm thick.
1/2 inch round for stud earrings.
They do not come with hardware.
All you need is stud backs and glue.
I'm offering them in a 10 pair pack and a 20 pair pack, you can pick the option you would like with the drop down bar.
They do have a protective covers on them that you need to remove before you press. It is a clear film.
Press 400 temp for 60 seconds hard press and done.
