Toolbox Icon with Blue Circle Background

This is a clean, modern icon featuring a crisp white briefcase or toolbox symbol. It's perfectly centered on a solid blue circular background, enhanced by a subtle, long shadow effect that gives it depth and a contemporary flat design feel. It's well-suited for representing business, work, professional tools, or portfolio sections in apps, websites, or presentations.
