Casual Line
The Casual Line and its aluminum bodies are soft. Because of their superior flexibility, these collar stiffeners are recommended for light shirts and for those who want to play around with the look of their collars.
Business Line
The Business Line features stainless steel bodies and are a bit stiff. Light color variations designed to match shirts and a restricted flexibility make these collar stiffeners the ideal choice for when you find yourself wearing a tie in a business setting.
