"Dear Mr. Kowalski, You are wasted in a canning factory. Please take these Occamy eggshells as collateral for your bakery. A well-wisher."
-- Message from Newt Scamander (WFT)
The pure silver eggshells are quite valuable and may be used as a potions ingredient.
- Occamy eggs are silver and have "lustre-giving properties" prized by potioneers (BoP).
- Used in the Felix Felicis potion invented by Zygmunt Budge (BoP).
- Newt Scamander's Occamy laid eggs inside his suitcase and a wayward Niffler left one of them on a bank bench. No-Maj Jacob Kowalski picked up the silver egg and put it in his pocket, where it hatched. When Jacob later lost his memories, Newt anonymously gave him a suitcase full of Occamy eggshells to finance his bakery business (WFT).
