I'm not sure if its actually 'Kaylan' material although it is from the company Kaylan.
When seeing 2 main types of mudflaps on ebay, normal or kaylan ones, is kaylan quite rigid or really floppy? (i know i'm asking for puns with that but please dont start)
This stuff is not rigid and really quite bendy.

I just used some scissors and took my time. some of the inside edges are not perfect but the outside edges are from the edge of the material itself

never really though about logos, and tbh I think my mudflaps are a bit short(or fitted higher) that there is not enough space for logos really.
