These are made from exactly what they look like. The tips of knitting needles. I saw the tips off, smooth them down, punch holes on both sides and I wire wrapped them to connect the sterling posts. They are approximately.98 and drop length makes them a little over an inch.
Some people are really rough on their knitting needles and since these are upcycled, they may show a little bit of use but I do my best to pick the least used looking ones. Being handmade, they may vary slightly which makes them unique and one of a kind.
