This is a thing?! That's why costco has it in different sizes?!

@twipped West coaster here...

The one on the right looks exactly like the butter I'm familiar with.

The butter on the left looks like the fancy Kerrygold stuff my wife buys for her *amazing* homemade bread.

I assumed it was a European or Irish thing...

East coasters - is it the opposite for you?

@robz it was, the first time I saw the shorter bricks after moving from michigan to california, I was like "tf is this? I don't have muscle memory for measuing this."
@twipped absolutely wild. Back when we weren't so connected as a country, our standards were weirdly regional.
