What you see is what you get: this 1/350 Hobby Boss kit is very nicely detailed and has all necessary photo etch included (railings!) With the included decals, it is possible to choose one from 10 different U-boats.
You can also use the PE name plate in a diorama. Though I did not do much research about this type of U-boat, I guess the only things that can really be improved are the guns and the periscope. I added PE handwheels and some other gun details using pictures.
