I had already found this seller's website but was unsure of the right size. Many variables - want them to sit up for display, the notch needs to be big enough and the stand needs to be sturdy enough not to tip over. And not too wide so that the prongs fit behind the tray.

I see they also have a 2.25" size but from your experience it seems that the larger one is the right one.

Thanks for the help.
