These had paper wrapping along them but it was torn up so I removed it. I have never used these. I'm not sure if this is abalone or a mother of pearl. It feels smooth to the touch and it is inlaid on two sides of every chopsticks three inlays on each side. Has some very small speckled stripes going along each chopstick. There are nine stripes on each chopstick. Appears to be some type of crushed shell possibly pretty enough. Each chopstick measures approximately 9 in and there are a total of six chopsticks three sets.
