ZKOO Poster & Bulletin Board Storage Bag 30 x 25 in, Extra-Large Waterproof Portfolio with Clear Window

ZKOO Bulletin Board Poster Storage is an extra-large, zippered portfolio bag that protects, organizes, and transports posters, bulletin boards, and oversized artwork up to 30 x 25 inches.

Whether you're a teacher hauling classroom displays, an artist moving prints between shows, or a scrapbooker protecting keepsakes, this ZKOO art portfolio provides a simple, weather-resistant way to store and find large-format pieces. Built from PVC and nonwoven fabric with reinforced nylon edges and handles, the bag balances durability with lightweight portability. A clear front panel and a middle pocket help you locate items fast while keeping contents safe from dust and light rain.

How does this storage bag protect large posters and bulletin boards?

The ZKOO portfolio uses waterproof PVC and tightly woven nonwoven fabric to block moisture and dirt. Reinforced nylon along the seams and handles reduces wear at stress points for longer service life. A full-length zipper keeps edges sealed and prevents items from sliding out during transport.

• Water-resistant PVC outer layer shields from splashes and dust
• Reinforced nylon handles and binding resist tearing
• Full zipper closure secures contents for safe transport
• Nonwoven interior reduces abrasion on delicate surfaces

Can I see what's inside without opening the bag?

Yes — the portfolio features a transparent front panel designed for quick visual checks so you can find projects instantly. That clear area also lets you display a single favourite sheet without removing it, useful when presenting sample work or labeling the bag's contents. It speeds up workflow in busy classrooms and studios.

• Transparent window for instant identification
• Easy display of one sheet on the exterior pocket
• Save time locating specific posters or boards

What size and capacity does the ZKOO art portfolio offer?

This model measures 30 x 25 inches, large enough for most standard posters, bulletin board sheets, and project boards. An interior or middle pocket of roughly 13 x 9 inches holds smaller supplies, labels, or flat reference sheets. The slim profile fits under easels or on classroom shelves while keeping contents flat and crease-free.

• Main compartment fits up to 30 x 25 inches artwork
• Middle pocket approximately 13 x 9 inches for smaller items
• Slim form factor stores easily in closets or under tables

How versatile is the bag for different uses?

The ZKOO portfolio is designed for a wide range of oversized materials: posters, scrapbooks, display boards, student projects, prints, and even layered collages. It performs equally well for transportation, short-term storage between exhibits, or keeping seasonal classroom displays organized year after year. Lightweight construction plus sturdy handles make it convenient for daily use or occasional moving.

• Suitable for classroom, studio, gallery, and home use
• Holds posters, bulletin boards, paintings, and large paper goods
• Portable for off-site presentations and art fairs

Who is this for? If you regularly handle oversized paper goods — teachers, student volunteers, art students, gallery installers, crafters, and event organisers — the ZKOO Bulletin Board Poster Storage bag offers a low-cost, practical solution to keep work flat, visible, and protected. It’s especially useful when you need quick access to projects, want to present a sample without exposing the whole stack, or require a weather-resistant carrier that won’t add bulk to your load.
