This is a set of red and black Esaki tissue decals that are partially cut out - meaning you get a sheet with the line work mostly cut but with little tabs keeping everything secured in the sheet. You have to release the tabs and then the part will be free to be doped onto your model (the model would be covered entirely in yellow in the CR3’s case). For the CR3 I use red Esaki which is not quite a bright a red as the CR3 originally had but when doped over a yellow it should be pretty close. The black is cut from black Esaki.
