Hey Kate,
I am so sorry about this!
Here are some tips to denest your cartons a little bit easier:
De-nesting - If you find you are having trouble de-nesting your egg cartons, try de-nesting them in counts of 5-10 before separating them individually.
The best way to de-nest these cartons is to gently shake them apart, rather than pulling them.
It is recommended to grab the bottom of the carton and the posts and shake them, rather than grabbing the sides or front flap.
Please let us know if this helps!
