Recently purchased stainless and nickel split rings from worth in size 2 and 3. I've always heard that stainless doesn't spring back like nickel does, but I've found with worth its the exact opposite ,the stainless do great.I even thought maybe they were labeled wrong .I tried testing them with a magnet because stainless won't stick to a magnet,but I found the stainless rings from worth do stick to a magnet, so they are stainless coated instead of pure stainless rings,the stainless didn't stick to the magnet as strong as the nickel so I knew they were labeled correctly so if anybody order's any I'd go with the stainless.
