THIS MASK IS A GOOD ALTERNATIVE TO USE DAILY USE MATERIALS ( THAT YOU CAN FIND HOME ) . JUST ADD STRINGS AND TNT, COTTON, POLYESTER AND IT WILL WORK FINE. OBVIOUSLY IT'S ONLY THE SUPPORT AND IF YOU PRINT IT IN TPU IT WILL FIT EASILY. IF YOU PRINT WITH HARD MATERIALS ( AS PLA OR RESIN STEREOLITOGRAPHIC ) JUST HEAT IT A BIT AND PUT IT IN SHAPE ON YOUR FACE
