These needles have a very smooth join, and the finish on the needles themselves have a very nice smooth surface. I also love the colors, I wish all needle manufactures would use some creativity with colors, creative people like creative tools.
Like Model Ts, they only come in black, I like the weight of the needle. They almost feel like plastic, but happily they are not. They do not get warm like plastic, but the stitches do not slip like the metal, yet move better than alot of bambo, or wood needles I have had in the past.
