Hi!
As it says on the description of Add or Remove 2 Eggsets, the item is applied through the Highlord Hub, not through Denarii Hub! Same applies to the Red Star pendant, as you need to only mention it when you enter the Hannibal's Raffle through Highlord Hub and it will be removed from your Inventory upon use; it can't be applied to a horse like a permanent item (ie. Companion or Heart Steak).
