I bought these before buying the small balls. These were bigger than what I wanted for my gumballs. I cut my bar just a tad bigger than 1". If your bars are thicker or you do cupcakes, these would probably work better for you than they did for me. I still love them, just not for the top of my bars. They are very sturdy and should last a long time. Easy and clean unmolding as long as your soap is NOT still soft. I have the patience of a gnat, so I dented a couple of balls.
