Red Wallet Portfolios are perfect for storing, protecting, filing, or transporting flat artwork when archival quality is not needed. Envelopes are constructed of a tough long-fiber paper that is durable, yet lightweight. Flaps have Velcro closures. Envelopes With Handles – Same as Red Wallet Portfolios, with plastic handles and no Velcro closure. Note – The sizes given for presentation cases, portfolios, binders, and refill pages are the sizes of the artwork it is intended for, not the actual dimensions of product.
