My Dad gets up and eats a bowl of ceral between 11pm and 2am every night! He loved this bowl and says the size is perfect! I would never have found a bowl I loved enough to give to him if I didn't stumble upon this site.
I bought this bowl as a gift for a cereal addict. It was a nice bowl, I'd say average cereal size. It won't fit a half box of cereal if that's what you're looking for. It came quickly and was just what I'd expected. Great gift!
