Japanese company REAL-f doesn’t just sell custom masks, they sells custom masks that look exactly like copies of human faces and heads.
The masks are created using “3DPFs” (3 Dimension Photo Forms), which are created by shooting a person’s face from various angles and then imprinting every detail onto a vinyl chloride resin mold. It literally copies the human face from freckles, pimples, blood vessels and all.
A 3DPF face can be yours for a mere $3,920 ($780 per additional copy), while an entire head goes for $5,875 ($1,960 per copy). Totally worth the price if you plan on wearing one and then robbing a bank.
