2024 mlb jersey

Hi everyone, I’m new to collecting and have a few jerseys I want to get signed. With the new jerseys that came out in 2024, I noticed the numbers are made of a kind of plastic print. I’m wondering:

1.  Is it safe to get autographs on the plastic numbers, or will the signature fade or smudge over time?
2.  Would it be better to have the player sign on the fabric instead?
3.  For these types of jerseys, is a Sharpie or a paint pen better for durability and appearance?

I’d really appreciate any tips or experiences you all can share. Thanks for the help!
