>>10804875all toys will degrade over time. this one probably faster than most, cause it's just paper. the Amazon AI aggregated reviews mention that the paper doesn't hold up well.
That said, nothing is really made to last anymore. We have certain toylines and releases that show visible deterioration in less than a year. And that's in the current year, when problems like that should have been solved long ago. And they were, but it cut into profits, so it's back to making shit as cheaply and shittily as possible.
My recommendation is stay away from this stuff. If you like the putting together aspect, take up Gunpla, it will at least have a better chance of survival. If you just want a big Iron Man head, save up for the wearable helmet, or get one 3D printed somewhere.
