Durable construction for longterm use The nylon straps and sealed edges are securely stitched to the mesh, boosting the strength of our art portfolio folders. The mesh construction provides greater durability than ordinary clear plastic bags, helping these folders hold up over time. Generous size for artwork storage The 19x25 vinyl combo bag accommodates up to 18x24 panels and can store two packs of 18x24x4/5 inch panels. Its ample footprint also makes it ideal for bulletin boards, posters, puzzles, charts, and more, reducing the need for multiple storage solutions. Reliable protection from the elements The watervinyl mesh zippered poster bags keep water, dirt, and scratches out, helping your items stay safe and clean even in rain or wet weather. Comfortable carrying and spacesaving design Wide shoulder straps reduce strain on the shoulders and hands when carrying items. The vinyl storage bags fold away or store flat when not in use, saving valuable space.
