Before the Smok Alien mod, ETALIENS made the first "Alien" mod and they're coming out with an updated version. I've always liked the HR Giger look of the style, especially the gunmetal. The new version can use a single 26650 or 18650 and also comes with a silicone case. I've seen them at https://www.heavengifts.com/product/ETALIENS-ET-X3-MOD.html
