There has been a fair amount of debate over the years on which is better, to make your own set of runes or to buy a set already made.
I have mixed feeling abut this as I am very creative and aside from my very first rune set, I have made all of my own sets out of various shapes and sizes of wood. That is my “preference”. However, near as I can tell, it makes no difference in a reading if you make your own or use a purchased set.
The Fates/Norns/Guides/”powers-that-be” are thought to manipulate the runes when they are picked or chosen in a reading to provide guidance to the seeker. So it should make little difference where the runes came from or how they were made.
