As I'm technically incompetent you will have to rely on someone else for a photo.
However, the material that you have seen as flash is part of the 3D manufacture process. It is like a frame on which the model is built. There are no air bubbles.
Clearly, these are not Tamiya quality models. But I would not want to use a high quality, fragile, kit on a games table. Besides, my modelling and painting skills are not of any great standard.
If you take a look on their site there is guidance on removing the excess material. I found removal was as straightforward as claimed and the model was ready for painting quicker than any of the other materials models are produced in. I can't recommend these to everyone as each person will have different requirements/ standards but I am happy with the end result and the carriers, in the early variant, are not available elsewhere in 1/56.
