Here is a really cool set of ROTS Sneak Preview figures from the SWJUNK Collection! These differ from the production versions in that the bubbles aren't as wide and they are attached to the card front on the sides, rather than being folded over and taped to the card backs like their production counterparts. There is still a small tab of plastic towards the bottom of the cards which folds over to the back. The plastic trays for each figure also differ in shape from the production versions and the positioning of the figures and their accessories also differ to varying degrees. The figures also appear to have paint differences from the production versions. From my research so far, this is one of only 2 of these sets known to exist.
