"1 pack of 6 (label says 5 but there are 6 in the pack) Classic in size 22 - 45lb (label says "Form fitting 100% cotton flannel, Concealed waterproof barrier)"
So RE: the type of nappy, I think the seller just got the Classics and Ultra's mixed up.
BUT... RE: the condition
Have been well used but lots of life left in them I'd ay
I don't class split and cracked PUL as "Lots of life left in them"...
I'd PM the seller about it and see where it goes from there.
