Review on ALSTON Wrapped Carbon 23X25X500Mm Surfaces Raw Materials by Ryan Hampton

I measured the diameter with cheap Chinese calipers. One rod was within ±0.12mm of the specified 25mm, the other was slightly larger (25.15 ±0.10mm). There were no stains or scratches on the surface. For the price I really can't complain, they're dull enough for what I'll be using them for (model airplane wing spar).
