I was playin' FR today and some old geezer in Cerulean gave me a Key Item that's some sort of jar... I checked pokemon forever and it's calleda "Konaire", but I don't know what that means... It seems to be a container though, I tried to use it and it said it was empty...

Before you say, it isn't the Berry Bag or TM Case 'cause I've got both of those.
