Hi, I am new to the 3D sublimation process and I'm looking to purchase some Jigs/Molds for cell phone cases. I have read lots of threads on here and it seems everyone is using all different types of molds for cases. I would like to know which molds you guys like better. I looked at Sun-Fly's website and seen numerous molds for the same phone. Can someone explain the difference between the blue colored and gold colored ones that they sell? I am in the US and from the sites I found here it looks like the iphone 6 and 6 plus molds are around $30-$40 each. Is this a good price? Thanks in advance for your help.
