Eco-friendly and vegan belt accessories: what’s actually worth it?

I’ve been seeing a growing number of belt accessories labeled eco-friendly or vegan....everything from buckles to small strap add-ons but it’s not clear what makes a product truly sustainable. Some use alternative leathers like cork or plant-based materials, others highlight recycled metals or lower-impact production processes. Browsing different suppliers even on Alibaba, I noticed similar-looking products marketed very differently, which makes it hard to tell what’s meaningful.

I’m curious how the community evaluates these items. Do you prioritize material type, ethical manufacturing, or brand transparency? And are there any brands or suppliers that consistently get it right without leaning too heavily on greenwashing?
