Waterbox cube 20 sponges

[Kika]

Hi all ! I got a WB cube 20 in the marketplace, but I need some of the filter sponges. I know they sale it, but I can’t wait for their delivery (takes few days) that said, I am looking for some Amazon alternative but I don’t know their size (WB does not specify the size of the sponges) can someone help me with some Amazon alternatives? Thanks in advance !

I got something before in Amazon that is oversized and just cut it to size. It's been a year since and I dont remember which one it was.
