Afternoon I really like the look of this and wondered if they could do one with a v4 logo (different 4 font so it can be machined obviously), and after hearing back from them, they can do a custom one for us with a minimum order quantity of 50 pcs, at £5 each. https://carbonwurks.com/shop/by-category/feature/carbonwurks-carbon-fibre-keyring/ Who would be interested in getting one? Can be on gloss or matt carbon and looks cool with the red loop.
I don't much fancy a bit of carbon fibre bouncing around. It would scratch the heck out of everything. I had something similar on my car key ring - it quickly wore a whole in the pocket of my jeans. Like so much in life, it's leather or rubber all the way.
Yeah it seems like this isn't a popular choice. I'll go with rubber. Then I'll buy a key ring wheeeeeeeyyyy!
