This stylish muscle car has not aged at all. (not that there is anything wrong with getting older & wiser, but these curves and lines do not look like they are almost 50 years old!). Durable, strong, & stylish - just like your classic. All products are made out of 12-gauge, brushed stainless steel. Bottle openers are about 4 inches in length. Visible lines are tiny cuts in the steel.
