Decals printed onto quality waterslide decal paper, the same as most custom decal designers use. They need to be accurately cut out of the backing sheet before being wetted and applied to the model. An inexpensive option for those that are familiar with using them.
Decals printed in a ‘film-less’ form that are similar to those in commercial kits. No need to accurately cut the decal out of the backing sheet because each element has its own 40 micron support film only large enough to support the elements of the decal such as text. They are easier to fit and give a professional look to your model.
