I finally got the seat post from TanTan. It took around 14 days to arrive, and the seat post is raw carbon with a glossy clear coat. They did say if I'm okay with it, they had it already produced, I'd say. Otherwise, by the looks of it, I would still be waiting because of the painting bottleneck. Doesn't look that bad, but I'll order a black matte one from them, and when it arrives, it arrives.
