Foam Board 22x28 25PK 3/8 Thick Foamcore Poster Board - Rigid, Acid

In this review the Foam Board 22x28 25PK 3/8 Thick from WHOLESALE ARTS AND FRAMES is judged as a practical, workhorse sheet for artists, teachers, and event sign makers; the single biggest reason to buy is the balance of rigidity and lightweight feel that makes mounting, framing, and displays straightforward. For anyone who needs a stack of consistent, acid free boards for presentations or crafts, this pack delivers useful size and thickness with a clean white surface that accepts glue, paint, and markers without obvious bleed.

Key Features

• 3/8 in thickness: Provides a rigid backing that resists bending for mounting artwork and temporary displays.
• Acid free white surface: Keeps photos and prints safe for framing and archival display without discoloration over time.
• Polystyrene foamcore construction: Lightweight yet dent-resistant for easier handling and transport of multiple boards.
• Large printable surface: Smooth face works well with markers, glue, screen printing, and paint for signage or school projects.
• Pack of 25: A cost-effective quantity for classrooms, galleries, or event production that need multiple backing sheets or display boards.

Who It's For

This foam board suits artists doing dry mounting or backing work, teachers preparing presentation boards or science fair displays, and small businesses creating temporary signage. Its white, smooth face and 3/8 in core make it especially useful where a rigid, clean surface is required but weight must be kept low.

Those who need precision-cut industry framing or unbendable, heavy-duty exhibition panels should look elsewhere, since customers report occasional dented edges, slight warping, and cut accuracy issues that make these best for general-purpose backing, craft, and display rather than exact-fit archival framing.

Pros & Cons

Pros

• Good overall build quality and a smooth printable surface that handles glue and markers well.
• Lightweight polystyrene core makes large sheets easy to carry and mount.
• Acid free construction suited for photo mounting and longer term displays.
• Bulk 25 pack offers strong value for classrooms and event prep.

Cons

• Some customers report occasional dents or crushed sides on delivery, so inspect on receipt.
• Cut accuracy and slight warping can appear, so it may need trimming for perfectly square framing jobs.
