OOAK, handmade custom Helmet from an insanely talented cosplayer in Spain.  This is the Portal Skin version of Zer0 from Borderlands.  Worn once for cosplay at Dragoncon and has been safely boxes since.  Helmet lights up in front as shown, looking like a Portal turret like in the actual Borderlands game.  Powered by 3 watch batteries (AG10/LR54/389) in screw shut compartment and has an external power switch.   Had very good visibility out of it when worn, maker was very attentive to that.  Grate panels also part of the design to help with airflow when wearing.  Battle worn finish while keeping clean aesthetic of the Portal mashup.

I also listed Zer0s sword.  Just in time for the return to cons!
