I'm looking at a page of instructions of my model and there exists a page of thin rods that I assume the instructions want me to make out of rolled paper or wire. What I'm confused about is how to interpret some of the markings. Almost all of the parts are labeled with what appears to be a size marking (e.g. some say 2szt. and others say 6szt.). What do these mean? Also, most parts don't give specific lengths. Do I have to just eyeball how long parts should be? Thanks!
