They are four single needles, Not double pointed. They look a lot like sewing needles but a lot bigger, They have the eyes the same as sewing needles. The eyes on these are big and Super easy to thread yarn through. The 2 bigger ones are the same size 2 5/8", The little ones are both 2".I had my husband measure lol I'm not very good with a ruler. Thank you for your question I hope I was able to help. :o)
