It is two bins. I have a tile between them so it is easy to pull the top one out if I need to clean it.RC I think I have asked ths before, sorry, but I don't recall your answer - are those nest bins double-lipped or is it two bins one in the other?
Cleaning was more of an issue when Diana was alive because she always laid eggs without any shell.
And the reason I need to double up is that if I take the whole thing out I have to shuffle stuff around to fit it back in and get the bedding out of the way. This way I just lift out the top. Clean it out. Restock with bedding and pop it right back. They are dishwashing bowls.
