Yeah most of them are over 20 years old today yet there is something underlying in the sculpts that does seem to show hands-on with the props or something.
It's unfortunate about the slight softness but fortunately it's not all that noticeable unless in closer macro pics or looking quite up-close at parts.
It's a little weird that even with the 1/6 explosion that's occurred in the past 15 years with the massive improvements in accuracy and realism, not to mention the 3D print and custom parts revolution in 1/6, that people would still be gravitating back to Marmit parts from 20+ years ago.
