Mini Fridge Frame

This frame is my first creation, designed to display just the photo of a instax mini frame. Slots in the back to add magnets (12x5x3 mm) for fridge or other surfaces. Glued, pressed, and weighed down magnets for secure fit. Ironing top surfaces enabled but not all suraces are the same smoothness. Any advice on improvements are appreciated, If purchasing magnets please use my link, it would be greatly appreciated: https://amzn.to/4sAauHZBoost MeBoost are very much welcome. Thanks in advanced.
