If these were from the ebay listing, there was an error in the title. They were really 2.5's all along, but still a good deal at $150 if they all work. You are getting them with the extended caps, but they aren't showing the original flat caps. If you want to run the medium size batteries, you can still get some of the end caps from the Provape parts guy, just make sure they have the small spring and not the larger one.Orange, red, and green. I was hoping for the Classics, but the listing was gone when I checked today and these three had turned up instead. For a lot less. They won't come with extension caps, but I bought an assortment of those as well. Thinking of pairing the Sangria purple cap with the green 2.5. I'm partial to that color clash.
