I tried one of my pots after one side of the duo shattered on one side when trying to place it into an empty palette. I first tried to get it into a 3 pan palette (both cardboard and metal) as well as an old 8 pan but no go.

It does fit in the single pots but just barely. I had to press the broken bits back into the pot once I got them in.

For the $20 cost you would think they would fit or at least come in a pot!
