Jazwares The Mandalorian Mask for Adults Black/Gray

Half The Mask, Twice The Fun
Protect Grogu, stop the Galactic Empire from rising again, and bring in a few hefty bounties along the way, all while wearing this Adult The Mandalorian Mask. You may not be as skilled as Din Djarin but you will certainly look just like him when you complete your Halloween costume with this accessory. The most notorious criminals in the star system will respect you and anyone with a target on their back will fear you while you wear this mask. 
Bring your bounties in warm or cold. All that matters is that you bring home a little bit of candy too. With an awesome mask like this, there's no way you won't be bringing home the sweets by the truckload. Of course, if trick-or-treating isn't really your thing anymore, then you could always bring home a win from your local costume contest! Just be sure to have your very own Grogu alongside you. 
Details Forged In Fire
While one may think this mask is made of the purest Beskar in the galaxy, it actually isn't. In reality, this mask is made of molded plastic. All the details only a master forger, like the Armorer, could create are included. A mesh view port on the mask allows limited visibility and breathability.
