I would recommend using a paper or linen towel inbetween the iron and the box.

I enjoyed your work and teaching me the knowledge you know. You made what someone would throw out to saving and reusing

This tutorial (although pretty verbose) was very helpful. I collect gunpla models, and sometimes get ones from Amazon that have been beaten up during shipping. I had one I seriously thought was going to need to be returned before I even opened it. But this knowledge actually really helped to get these boxes back into shape. To add to it, you can actually take a small brush used for gluing models, thin one ply toilet tissue, and super glue to patch up parts of cardboard or paperboard boxes like this.

Never thought about doing that. I'm going to give it a try.

Defenatley a vast improvement.

That's pretty slick John!

Excellent tutorial, I did wonder how you repaired your boxed games with the iron! The only time I tried to iron a gaming item was when I tried to take the creases out of a Sega Master System manual. Sadly that just resulted in the paper being stained and the ink running.

Finally a reason for men to use an iron! Great idea! Subscribed.

I tried this on my Pokemon Emerald box, it worked pretty well. Just be careful not to burn the box as gba boxes are really thin.
