This collage photo mat board is designed to display eighteen Instax Mini photos inside a standard A3 frame. It gives your favourite instant prints a clean, organised layout without needing a custom picture framing job.

The window openings are cut to 4.2x5.8cm, designed to show the photo image area of each Instax Mini print while covering most of the white border. Each mat board is precision cut in Australia from premium acid-free mat board, with crisp bevel-cut windows and a white core for a neat professional finish.
