Where can I get a reusable super king jumbo egg carton?

My commercial hybrid hen lays large 90g+ eggs every day, sometimes over 100g, and I'm struggling to find a way to store them in the fridge neatly and safely. I have an 800g jumbo egg carton but it simply isn't large enough. I need to use alternate spacing because there isn't enough space to sit next to each and the lid is a LONG way off from being able to close so I can't stack. The eggs are usually between 15.5-17cm in circumference.

I've considered duck egg cartons but can't find anywhere online that will sell only 2 cartons, I don't need bulk buy. I'm not sure if a duck egg carton would be the right size either, the eggs are very fat and oval shaped, no pointy ends. I'd prefer a reusable option and not to use a pulp carton as I need it to last a long time but if it's my only option then I'm OK with that. It needs to have a lid too.

Can anybody recommend somewhere that sells single cartons?
