Review on 🎨 Optimized for SEO: Lightweight Art Portfolio Bag, 24 x 36 inches, with Nylon Shoulder Strap - Ideal for Poster, Sketch, and Drawing Storage - Convenient Handle and Zipper Closure by Summer Hendricks

This is a really big poster pocket. I am a teacher and was able to put up all my posters and wall decorations (no borders - they would be too long for that) without any problems. Keep in mind that the material is in no way rigid or thick. It won't get up on its own. You either have to lay it flat, stuff it between two filing cabinets to store it, or do what I did and put a large, sturdy piece of cardboard inside. I put cardboard in the middle and posters on the sides. It's big and strong enough to hold the bag upright so you can lean on things.
