[Vocabulary] 'due in no small part to'

[wotcha]

"This is due in no small part to the nearly infinite variety of Barbie "accessories and apparel" available,

as well as all those infamous "specialty" Barbies, including California Barbie, Circus Barbie and Cowgirl Barbie."


Though I've looked over some dictionaries I can't exactly understand what the red phrase in the sentence

means.


I know "due to" means "because of", but have no idea about "due in"


Please, enlighten me!

Thank you.

The phrase is still "due to" but an extra bit has been added: "in no small part", which serves to emphasise how much it is because of something; the infinite variety of Barbie dolls in this instance.

The phrase however, is a little formal and only really found in writing.

This is due (in no small part) to the almost infinite variety of accessories available.

It shows that the infinite variety of accessories which are available is a large part of the reason for something else (whatever it is that "This" refers to in the sentence).
