This is a completely unused and new (albeit open box) white PCIE Gen 4 Riser Cable. It has a right angle female connector, and is approx 8 inches in length (200 mm). It was bought from Amazon from Vetroo but I never ended up using it.

Here's the current listing on Amazon, it's $34.99 with free shipping: https://www.amazon.com/Vetroo-Shielded-High-Speed-Flexible-Extender/dp/B0B6DSMTW6

Therefore I'm giving you an over 30% discount considering it's unused.
