Premium Black PEI
We searched long (I mean very very long) for a reliable source for the original premium black ULTEM™ based PEI!
Finally we found it! Although the black gold usually is only sold in industrial scale we found a way to get serious supply, but not 40ft container full of of it! The PEI is called Superio™ and is manufactured in Japan.
