Craig Frames B402 Pre-Cut Mat Board for 12x12 Print - Clean White Mat

In this review the Craig Frames B402 pre-cut mat board is assessed for anyone framing a 12x12 image to display in a 20x20 frame. The bottom line: this mat is for hobbyists, photographers, and crafters who want a neat, archival-looking presentation without professional framing services because it combines a smooth white face, a light cream core bevel, and pH neutral construction that keeps prints flat and looking polished.

Key Features

• Pre-cut opening: The mat is cut to fit a 12x12 print while the actual opening is slightly smaller at 11.5x11.5 in to prevent the photo from slipping through.
• Frame compatibility: Designed to fit a 20x20 frame so users can match the mat to standard frame sizes without trimming.
• Smooth white finish: The face presents a clean, neutral backdrop that helps images stand out and keeps attention on the print.
• Cream core bevel: A 0.05 in cream core bevel adds a subtle visual edge that enhances depth and framing aesthetics.
• Archival quality: pH neutral matboard preserves prints and maintains a professional appearance over time.
• Made in the USA: Single-opening custom-cut matting manufactured domestically for quality control and consistency.

Who It's For

This mat is best for DIY framers, scrapbookers, small studio photographers, and crafters who already own or plan to buy a 20x20 frame and want a ready-to-use white mat that highlights a 12x12 image. It suits anyone who prefers a smooth white face with a subtle cream core to add depth without distracting from the artwork.

Those who need nonstandard sizes, double mats, or bespoke archival mounting techniques should look elsewhere; this listing includes a single custom-cut, single-opening mat only and does not come with a frame or professional mounting service.

Pros & Cons

Pros

• High quality construction with a smooth white face that looks clean and professional.
• The 11.5x11.5 in actual opening prevents prints from falling through while still displaying a 12x12 item neatly.
• pH neutral board and a cream core bevel give a refined presentation and help protect the print.
• Made in the USA for consistent cut and finish.

Cons

• Only a single-opening mat is included and the frame is not supplied, so additional purchases are required to finish the display.
• If you need exact full 12x12 visibility without the 0.25 in reduction on each side, this mat slightly crops the visible area.
