I know a married couple who each have identical twin siblings. The identical siblings also married each other. The children of each couple, who are cousins, definitely look more like siblings than cousins.

There was a story about a pair of twins like that in the Washington Post recently: https://www.washingtonpost.com/lifestyle/2022/08/24/virginia-twins-married-salyers/ https://www.washingtonpost.com/lifestyle/2022/08/24/virginia... The marriage is known as a quaternary marriage, and the cousins are known as quaternary twins.

Genetically speaking, all of the children from both couples are indistiguishable from siblings.
