The Inart A1 Black Drawing Portfolio with Handle and Closure (078490611) is a durable polypropylene portfolio designed to transport and protect large-format artwork without bending or damaging it along the way. It includes a carrying handle, an optional shoulder strap for longer trips, an interior pocket on one side and an elastic band on the other to secure artwork, as well as plastic feet to protect the spine when the portfolio is placed on the floor. The A1 size, the largest in the range, is ideal for transporting posters, technical drawings, or large-scale paintings between the studio, school, or exhibitions. It is suitable for architecture, design, and fine arts students who regularly work in large formats and need a secure means of transporting their work.
