fashion 3d diy blank sublimation hard pc white matte and smooth cover full area printed for iphone 11 pro max iphone xr xs max sam note 10

3d shell can not be installed before it is printed, it will be a few millimeters larger, but it needs to use the corresponding mold. use the steaming machine to put the 3d shell on the printing mold and vacuum it. it can be colored until 185 degrees and 300 seconds, and it can be installed after shrinking. the heat press machine cannot print 3d shells. thank you .
