FS: New, never mounted Ultegra 8000 Chainrings-make offer

I have a 53-39 chain rings for an Ultegra 8000 crank that never got used as I am running single ring set up. These are new and never mounted. Includes chainring bolts.
Not really sure what to price these at and it's likely this isn't a high demand item so if you need these make me a reasonable offer.
