That's a good question. I've never thought about it. I know LV has some bags that are customized or monogrammed but I don't know if it's dyed or painted. I would be interested in hearing others opinions about this myself.
I would imagine that with paint, it would wear off with use over time.
How funny.... Only last night randomly on IG a pic came up of a Chanel/LV authenticator and she painted her used and abused chanel wallet with hot pink leather pink and it looked amazing. That was caviar leather though I think, I also wouldn't know how saffiano would hold up? Can you buy a cheap charm in the sales to try it on first? I didn't even know such paint existed until last night [emoji1]
