Titanium needle used. Available in 2-needle and 3-needle configurations. The needles are light, strong, and sharp. These are strong needles. I also use them for Tai Rubber fishing. I think the light needles allow for good suction. The rigs have a proven track record, with two standard morning colors: orange-based. Repeat customers and buyers have also commented on their success. Although they are size 10 hooks, they are quite strong. ☆ Standard Morning Colors * Orange Zebra and Orange ☆ Please understand that these are handmade. ☆ Sea Braid 5-strand, sinking type for large fish ☆ Titanium Needle Size 10, 2-needle and 3-needle ☆ Tai Rubber Necktie S-type * Orange Zebra * Orange ☆ Luminous rubber for necktie stopper * Effective in murky water and deep areas.
