ZKOO 20 x 26 Inch Art Portfolio Bag, Big Art Portfolio Case Light Weight Waterproof Poster Board Storage Bag, Artistic Collection Tote for Artwork, Poster, Sketch Drawing, Canvas (20"*26"-Black)

How do I choose the right size?

The size listed in the product name refers to the maximum artwork size that fits inside. For example, the "18×24 inch" bag has interior dimensions of 24"L × 18"H, which means it comfortably holds artwork up to 18×24 inches.

Is this bag rigid or soft? Does it have a hard board inside to protect my artwork from bending?

This is a SOFT-SIDED portfolio bag made of flexible 420D nylon fabric. If your artwork is loose paper or thin sketches that need bending protection, we recommend inserting your own cardboard or foam board inside the bag — many customers do this.

Does this bag have a chemical smell? Is the material safe and odor-free?

Some customers have noticed a mild odor when first opening the bag. This is common with new nylon products that have a waterproof inner coating it's what protects your artwork from rain and moisture., and it is NOT harmful.

I need to carry multiple items or thicker materials. Will this bag work for me? Which size should I get?

Many buyers who purchased the 18×24 size and found it too snug exchanged it for the 20×26 size and were much happier. When in doubt, always go one size up — always carry smaller items in a larger bag, but you can't fit larger items in a smaller one!

What can I use this bag for? Is it suitable for my needs?
