This is a highly modified Fire Maple HX Kit: the Star 1. Weight was originally almost 19 oz has been reduced to 10.4 oz. Plastic shielding and ignitor were removed, and the mug was trimmed down to a maximum volume of 830 ml. Fairly light and super-efficient. Shipping weight over 13 oz so it will have to ship Priority Mail:shipping should be around $8 West Coast and $16 East Coast. Actually shipping cost may vary a bit.
