Asking more generically for anything made of faux leather, not necessarily this item in particular, but I gotta admit this multitool is pretty handy at times and is part of my everyday carry.
I’m more asking, like how to best treat faux leather for longest lasting and best surface? Like, what happens if it gets wet? Is shoe polish or oils or something beneficial to keep the surface intact?
It is a generic name for a variety of materials, usually PVC or PU, which are essentially maintenance-free other than occasional cleaning with warm soapy water. Avoid prolonged exposure to UV and abrasion. Should last a very long time.
If it’s a more exotic faux leather made from biodegradables / renewables it’s going to break down over time because it’s meant to.
In short, it’s very unlikely you need to regularly condition it like real leather.
