L'Oreal
The worst makeup company on Earth. They promise big money to their suppliers and then laugh in their faces when they don't deliver. Their quality people are like monsters who pick apart every little thing with no mercy.
My supplier just got rejected for a L'Oreal order because the lipstick was 0.01mm too pink.
L'Oreal's quality team is like a group of sadistic elves who only like perfection.
I tried to deliver 10,000 lipsticks and they rejected all of them because the packaging wasn't 'spicy enough'.
