Hello Marco,
@Ian Grant is correct. I cut down and respool 120 film to use in an Ensign Midget camera. The Midget takes 35mm wide film but I prefer not to see sprocket holes on the larger negatives produced by the Midget so I cut down 120 film. This also gives me a supply of backing paper which the camera needs in order to work properly.
I believe your Ensignette - which is a different camera - takes a wider film size. In fact it seems the different models take different sizes. Have attached an advert from Flickr.
You will see that the 2 models of Ensignette create different sized negatives, and presumably took different sizes of film.
I don't have an Ensignette right now so I can't compare the sizes, but the convertor linked above looks like a very good starting point. Just remember to cover the red window unless you also include some backing paper. (I have used other adaptors from that Ebay seller, Bid-With. The adaptors arrived safely and are excellent quality).
Cutting roll film down to size is not difficult. However, finding extra take-up spools for these little cameras can be much, much harder.
I began this adventure using guidance from ArtDecoCameras.com He has a list of formats that, sadly, does not include the Kodak 128 E1/E2 format.

If your cameras come with spools you can measure these for a definative answer to the correct size. Cutting film to fit will then not be difficult.
I can't offer to cut down and respool film for you as I doubt it would reach Italy without exposure to xrays, or worse

.
Good luck with project. They are fun little cameras to have in your pocket!
