I bought a set of items that previously contained bars and bone tip caps, but they were unused. This set should be inexpensive with only sets of parts that are used frequently. I also want to purchase.
There was a brass pin and it was supposed to be plugged into the metal fittings, but I inserted a stainless steel wire on hand without entering anyhow. Besides this, any metal fittings were easy to use and packaging was simple and good.
