Depending on the height of these and the gap between shelves it might be worth thinking about making something like a row of steps to sit them on ??
( Like seats / bleachers at a stadium )
I have them sat on the egde of the shelve at the moment so I can have the taller ones at the back and these small ones at the front. There another picture I posted that has the layout I went with
