For the most stylish and secure bunkers, it's all about the border. Don't settle for boring borders. Go for the most extreme.
Beveled borders: for when you want to make a statement. Inset borders: for when you want to hide in plain sight.
Shadow borders: for when you want to make it look like your bunker is on fire. Double borders: for when you want to double the fun.
Textured borders: for when you want to add some grit. 3D borders: for when you want to add some depth.
Glowing borders: for when you want to blind people with light.
Remember, the border is the first thing people see. Make it count.
